Dispute a car rental charge: the complete guide and letter templates

Everything you need to get your money back, in order, whichever company you rented from and wherever in Europe you rented. Every template has been used on a real case. Replace the [ ] placeholders with your own details, copy, send.

Faster: let the portal write them for youThe templates on this page are the raw version, with placeholders. File your case in four steps and you receive the same five letters already filled in with your details, matched to your rental company, to the country you rented in and to your dispute type, with no placeholders left. Ten minutes, free, no commission and no power of attorney: you send them yourself, from your own mailbox.
The principleFive independent levers, launched in parallel. The company has to hold all of them shut; you only need one to give way. And the prerequisite to all of them is the written complaint to the company itself (step 2).

0. Build your evidence file first

Every procedure will ask for the same documents. Gather them once, ideally as a single PDF with a one-page summary:

  1. The contracts: rental agreement, closing document, final invoice. If they were never sent to you, ask for them in writing. A refusal is already an argument.
  2. Proof of payment: card transaction details (prepayment, deposit held, disputed charge). Your statement also shows the IBAN the European Consumer Centre will ask for.
  3. The correspondence with the branch, as one chronological PDF.
  4. Your time-stamped photos, at pick-up and at return: all four sides, fuel gauge, odometer, interior, and the car park ticket where relevant.
  5. Proof of return: signed condition report, time-stamped ticket, or tracked proof of posting for the key.
One piece of honest adviceOnly claim what is genuinely disputable. If the tank was not full, concede the fuel, but ask for it to be deducted from the fuel deposit you already paid rather than charged on top. A slightly smaller but watertight file beats an inflated one every time.

1. Identify your dispute type: it drives everything

This is the most expensive mistake in these cases: sending a generic letter. A customer service agent dismisses in three lines a letter about vehicle return when the dispute is about a deposit. Each type has its own facts and its own legal grounds:

  • Charges after the vehicle was returned: the "rental" keeps running on a car you already gave back.
  • Deposit not released: a guarantee kept without an itemised account or proof of loss.
  • Damage charged with no contradictory inspection: the burden of proof lies with the professional.
  • Fuel charged twice: deposit retained and fuel invoiced on top of it.
  • Insurance or extras forced at the counter: a service you did not request is not owed.

In the templates below, the facts block and the grounds block change according to your dispute type. Both sets are given in step 2.

2. The formal complaint to the rental company

To: the email address of the return branch, which appears on your rental agreement and on your invoice. Cc: the national or European customer service of the brand. Write in English: it is the working language of branches across southern Europe.

With a large brand, add the group's consumer service: the local branch almost never has the authority to refund. Brand ownership is listed on the rental companies page.

Subject: Formal complaint / Refund request / Booking [BOOKING NUMBER] Dear Sir or Madam, [THE FACTS: use the block matching your dispute type, below] [THE GROUNDS: use the block matching your dispute type, below] I therefore formally request the refund of [AMOUNT] EUR to the payment card used for this booking, within fourteen (14) days of receipt of this letter. Failing a satisfactory response within that period, I will refer the matter to [OFFICIAL REMEDY OF THE COUNTRY YOU RENTED IN, e.g. the Portuguese electronic complaints register (Livro de Reclamacoes)], the European Consumer Centre of my country of residence, and my bank, for a chargeback. I reserve the right to instruct legal counsel under my legal expenses insurance. This letter is sent without prejudice to any of my rights. Yours faithfully, [NAME] [POSTAL ADDRESS] [EMAIL]

The "facts" block, by dispute type

Charges after the vehicle was returned
I rented a vehicle ([PLATE OR MODEL]) from [COMPANY], [BRANCH] branch, under booking [BOOKING NUMBER], from [START DATE] to [END DATE]. I returned the vehicle to the agreed location at [EXACT PLACE] at [TIME], before the contractual end of the rental, and I notified you in writing on the same day. Your office was closed at that time and no key drop-box or out-of-hours return procedure had been made available to me, although my departure flight time was known to you at the time of booking. On [CHARGE DATE], [AMOUNT] EUR was debited from my payment card without prior notice and without my agreement.
Deposit not released
I rented a vehicle ([PLATE OR MODEL]) from [COMPANY], [BRANCH] branch, under booking [BOOKING NUMBER], from [START DATE] to [END DATE]. A security deposit was taken on my payment card at pick-up, as a guarantee and not as a payment. I returned the vehicle at the agreed place and time, in the condition in which it was handed over to me. The deposit was not released. [AMOUNT] EUR was retained, without any itemised justification and without any document evidencing an actual loss on your side.
Damage charged with no contradictory inspection
I rented a vehicle ([PLATE OR MODEL]) from [COMPANY], [BRANCH] branch, under booking [BOOKING NUMBER], from [START DATE] to [END DATE]. On return, damage was charged to me for [AMOUNT] EUR. I dispute it. No contradictory condition report establishes that this damage did not exist when the vehicle was handed over to me, and no repair invoice has been produced showing an actual cost matching the amount charged. On [CHARGE DATE], [AMOUNT] EUR was debited from my payment card without prior notice and without my agreement.
Fuel charged twice
I rented a vehicle ([PLATE OR MODEL]) from [COMPANY], [BRANCH] branch, under booking [BOOKING NUMBER], from [START DATE] to [END DATE]. I returned the vehicle with the fuel level required by the contract. [AMOUNT] EUR was nevertheless charged for fuel, in addition to the amount already retained on my card as a fuel deposit, which amounts to charging the same item twice. On [CHARGE DATE], [AMOUNT] EUR was debited from my payment card without prior notice and without my agreement.
Insurance or extras forced at the counter
I rented a vehicle ([PLATE OR MODEL]) from [COMPANY], [BRANCH] branch, under booking [BOOKING NUMBER], from [START DATE] to [END DATE]. At the counter, insurance cover and options that were neither booked nor necessary were added to my contract, presented as compulsory or as a condition for handing over the vehicle. I did not request these services and I was not given the opportunity to refuse them in an informed manner. On [CHARGE DATE], [AMOUNT] EUR was debited from my payment card without prior notice and without my agreement.

The "grounds" block, by dispute type

Charges after the vehicle was returned
This charge is disputed on three grounds. First, a service that was not provided cannot be invoiced. The vehicle was returned to the agreed location and remained immobilised there, to your knowledge. No rental service was rendered during that period. Second, you are under a duty to mitigate your own loss. You knew the exact location of the vehicle from the day of the return. Any delay in recovering it is attributable to your own organisation, not to me. Third, a contractual clause cannot authorise charges determined unilaterally after the end of the rental, nor exempt you from your pre-contractual duty to inform, in particular as to the absence of any out-of-hours return procedure.
Deposit not released
This retention is disputed on three grounds. First, a security deposit is a guarantee, not a payment. It must be released once the customer's obligations have been performed. Keeping it requires you to establish an actual, quantified loss, item by item. Second, the burden of proof lies with you. In the absence of a contradictory condition report and of any supporting invoice, nothing establishes the existence, the extent or the cost of what you claim. Third, a clause allowing a professional to keep a fixed sum without proof of loss and without contradictory assessment is a disproportionate penalty, which is precisely the kind of term consumer law treats as unfair.
Damage charged with no contradictory inspection
This charge is disputed on three grounds. First, the burden of proof lies with you. It is for the professional to establish that the damage did not exist when the vehicle was handed over. A check-out report drawn up in my absence, or in a poorly lit car park at night, does not meet that standard. Second, what may be charged is the actual repair cost, evidenced by an invoice, not a fixed amount taken from an internal damage grid. A predetermined sum without any link to the real cost is a penalty, not compensation. Third, I was not given the opportunity to have the damage assessed contradictorily before being charged for it, which deprives me of any means of contesting its extent.
Fuel charged twice
This charge is disputed on three grounds. First, fuel may only be charged for what was actually consumed and not returned. Charging fuel while also retaining a fuel deposit charges the same item twice. Second, any administrative or service fee must correspond to a service actually rendered, and its amount must be proportionate to that service. Third, a fuel policy which structurally results in the customer paying for fuel not consumed creates a significant imbalance between the parties, to the detriment of the consumer.
Insurance or extras forced at the counter
This charge is disputed on three grounds. First, a consumer owes nothing for a service that was not requested. Adding cover or options at the counter, presented as compulsory, is an unrequested supply. Second, presenting an optional cover as a condition for handing over a vehicle already paid for is an aggressive commercial practice: it uses the pressure of the moment, at the end of a journey, to obtain a signature that would not otherwise have been given. Third, your pre-contractual duty to inform requires that the price and optional nature of these services be clear before the booking is made, not at the counter.

2b. When the company "justifies" the charge

Customer service replies are standardised, and most of them contain an admission. The classic one, on a post-return dispute: "the costs are due to the car being parked at the airport until that date… the system corrects to the day the car was actually collected". In other words, they confirm the car was parked throughout the period billed as "rental". Check as well whether their breakdown matches their own invoice and the amount actually taken. Often it does not.

Subject: Re: Formal complaint / Booking [BOOKING NUMBER] / your explanation does not justify the charge Dear [NAME], Thank you for your reply. It does not withstand scrutiny. 1. Your own answer confirms my point. [QUOTE THEIR SENTENCE]. That statement establishes that no service was provided during the period charged, and I ask you on what contractual basis it was invoiced. 2. Your breakdown does not match your own documents: on the invoice of [DATE], [AMOUNT] EUR is itemised as [LABEL A]; in your email the same amount has become [LABEL B]. Neither your total nor your items match the [AMOUNT] EUR actually debited. Please send a single, itemised statement. 3. If an actual disbursement was incurred on your side, send me the receipt. I will consider a documented expense, not an unspecified round figure. My claim therefore stands: refund of [AMOUNT] EUR by [DEADLINE]. For good order, this matter is already the subject of [complaint no. [REFERENCE] before [AUTHORITY]], a complaint to the European Consumer Centre, and a payment dispute with my bank. Your reply has been added to each file. Yours sincerely, [NAME]
The habit that paysNever argue on the phone. Anything that is not in writing does not exist for the rest of the procedure, and consumer authorities read documents, not accounts of phone calls.

3. The official remedy of the country you rented in

This is the step that produces the strongest reaction, and the one most people never hear about. It is free, it forces the company to answer, and it leaves a trace with an authority. Mind the country: not your country of residence, not the country of the brand's head office, but the country where the branch is located.

Country of rentalFree official remedyWhat it triggers
PortugalElectronic Livro de Reclamações, livroreclamacoes.ptMandatory reply within 15 working days and automatic transmission to the sector regulator
SpainHoja de reclamaciones, then consumer arbitrationFiled with the consumer office (OMIC) of the autonomous community; arbitration is free and binding on companies that adhere to it
ItalyChamber of commerce conciliation, report to the AGCMFree conciliation procedure; the AGCM sanctions repeated unfair practices
GreeceConsumer OmbudsmanFree handling of disputes with traders established in Greece, filed online in Greek or English
FranceSignalConso, then consumer mediationThe trader is notified and the DGCCRF sees reports accumulate; mediation is free
BelgiumFPS Economy and BelmedReport to the contact point and online mediation, both free
CroatiaMandatory written complaint, then the consumer protection authorityThe trader must allow a written complaint and answer it in writing
Elsewhere in the EUNational consumer protection authorityThe European Consumer Centre in your country will give you its contact details and can refer the case for you

The text to file, valid for all of these

Complaint against [COMPANY] ([BRANCH]), booking [BOOKING NUMBER]. Trader: [EXACT LEGAL NAME, ADDRESS AND TAX IDENTIFICATION NUMBER, as they appear on your rental agreement]. [THE FACTS: reuse the block matching your dispute type, step 2] [THE GROUNDS: reuse the block matching your dispute type, step 2] I have already sent a written complaint to the company on [DATE]. I request the refund of [AMOUNT] EUR, and I ask the authority to note that this practice appears to be recurrent at this branch. [NAME] [POSTAL ADDRESS] [EMAIL]
Never invent a tax identification numberAn official complaint filed with a wrong identifier gets rejected, and you lose weeks. That number is always printed on your rental agreement and on the final invoice. Do not take it from a forum.
Step by step: the Portuguese Livro de Reclamações
  1. Go to livroreclamacoes.pt and choose "Make Complaint", not "Information Request": check the URL contains /Pedido/Reclamacao.
  2. Profile: consumer. The "Tax Identification number" field expects your personal tax number, not a company VAT number. Document type: "ID Cidadão Estrangeiro" or "Passaporte Estrangeiro".
  3. Identify the trader: advanced search, VAT Number field, using the number printed on your contract.
  4. Service: "Aluguer de Veículos de Curta Duração". Subject and reason: "Faturação incorreta" for a billing dispute. Advertising: No.
  5. Complaint text: plain characters only. The site rejects the euro symbol, long dashes and curly quotes. Write "EUR", "-" and standard quotes.
  6. Attach your evidence PDF if the form allows it, submit, then confirm through the link sent by email (valid 24 h, single use), option "Submeter sem criar conta".
  7. You receive a ROR000… number: that is your official reference. Download the receipt ("comprovativo", link valid 3 h).

4. European Consumer Centre (ECC-Net)

Free, in your country of residence. The ECC forwards the case to its counterpart in the company's country, which contacts the trader directly. Highly effective on car rental disputes, on one condition: the trader must be established in a country other than yours. If you rented in your own country, the right channel is the consumer mediator the trader belongs to, whose details must appear in its terms and conditions.

Forms: eccnet.eu lists every national centre. The form asks for three texts: what happened, what you expect, what you have already done. It often accepts a single file per category, so merge your evidence into four PDFs (contracts, payments, correspondence, photos).

Subject: Cross-border dispute with [COMPANY], booking [BOOKING NUMBER], [AMOUNT] EUR Dear Sir or Madam, I am asking for your assistance in a cross-border dispute with [COMPANY], [BRANCH] branch, a trader operating in [COUNTRY OF RENTAL]. [THE FACTS: rental from [DATES], booking [NUMBER]. Describe what happened in three to five dated sentences. Then: on [DATE], [AMOUNT] EUR was debited from my card without prior notice and without my agreement.] These charges do not correspond to any service properly provided and agreed. I sent a written complaint to the company on [DATE], which has not been resolved satisfactorily. I would be grateful if you would refer the matter to your counterpart in the trader's country in order to obtain the refund of [AMOUNT] EUR. I remain at your disposal for any further document: rental agreement, invoice, bank statement, time-stamped photographs and correspondence with the branch. Yours faithfully, [NAME] [POSTAL ADDRESS] [EMAIL] [IBAN]

5. Chargeback

This is a card payment dispute, not a direct debit to cancel. On the phone, banks often answer "you signed the contract, there is nothing we can do". That is wrong: your signature only authorises charges that comply with the contract, and card scheme rules provide dispute reasons for services not rendered and for additional charges applied by a rental company. Put it in writing to the bank's complaints department and insist on a written, reasoned refusal: that refusal is what opens the door to the banking ombudsman.

This is the shortest deadline in the whole file: 60 to 120 days after the charge. If yours is more than two months old, start here.

Subject: Dispute of a card transaction dated [DATE], [AMOUNT] EUR Dear Sir or Madam, I formally dispute the following transaction debited from my account: Merchant : [COMPANY] ([BRANCH]) Date : [CHARGE DATE] Amount : [AMOUNT] EUR Booking : [BOOKING NUMBER] [THE REASON: pick the sentence matching your case, below] I ask you to open a chargeback with the card scheme on the grounds of "services not provided" and "unauthorised additional charges", these schemes providing a specific reason code for charges applied by a car rental company after the vehicle has been handed back. I enclose: the rental agreement, the company's invoice, the bank statement showing the charge, and the written complaint I sent to the merchant. Should you refuse, please notify me of that refusal in writing and with reasons, so that I may refer the matter to the banking ombudsman. Yours faithfully, [NAME] [POSTAL ADDRESS] [PHONE]

The "reason" paragraph, by dispute type

Charges after the vehicle was returned
This transaction corresponds to charges applied unilaterally AFTER the rented vehicle was returned, for a period during which it was immobilised at the agreed location, to the merchant's knowledge. No service was provided in return and I never authorised this amount.
Deposit not released
This transaction corresponds to the retention of a security deposit that was a guarantee, not a payment. The merchant kept it without producing an itemised account or any document evidencing an actual loss. I never authorised a payment of this amount.
Damage charged with no contradictory inspection
This transaction corresponds to damage charged unilaterally, without any contradictory condition report establishing that it did not exist when the vehicle was handed over, and without any repair invoice justifying the amount. I never authorised this amount.
Fuel charged twice
This transaction corresponds to fuel charged although the vehicle was returned at the required level, and although an amount was already retained on the same account. The same item is charged twice and I never authorised this amount.
Insurance or extras forced at the counter
This transaction corresponds to insurance and options added at the counter, which I had neither booked nor requested, presented as a condition for handing over a vehicle that was already paid for. I did not freely consent to this amount.

In Belgium, France and several other countries, legal expenses cover is very often included in a car or household policy without the holder knowing. It covers consumer contract disputes: the insurer appoints a lawyer at its own cost, who sends a formal notice to the rental company. One email to your broker is enough.

Subject: Legal expenses cover? Car rental dispute, [AMOUNT] EUR Hello, Could you check whether my policy includes legal expenses cover and, if so, open a file? The dispute is with [COMPANY], a car rental company, [BRANCH] branch ([COUNTRY]). [AMOUNT] EUR was charged to my card on [DATE] without my agreement. [THE FACTS: three to five dated sentences, as for the European Consumer Centre.] I have already sent a written complaint to the company on [DATE] and started proceedings with the competent authorities. Opposing party: [EXACT LEGAL NAME, IDENTIFICATION NUMBER, ADDRESS, as they appear on the contract]. Could you confirm whether this cover is included, and which documents you need? Many thanks, [NAME] [PHONE]

7. What if nothing moves?

  • No reply to the official complaint within the legal deadline: go directly to the sector regulator, which has already received the complaint. In Portugal that is the AMT (Autoridade da Mobilidade e dos Transportes) for rental disputes.
  • An unsatisfactory reply: move to consumer arbitration or mediation in the country of rental. Free or nearly free, and binding on traders that adhere to it.
  • A written refusal from your bank: the banking ombudsman in your country, free of charge.
  • And above all: file your case here. The more files accumulate against one company, the more seriously the authority, the European Consumer Centre and the press take the subject. One isolated case gets negotiated; a hundred documented ones get settled.
The honest forecastOn a well documented file: a settlement, often partial, within three to six weeks in most cases. The chargeback is the least reliable lever; the official national remedy, the European Consumer Centre and legal expenses insurance are the ones that move things.
The same happened to me
