Booked through a platform? Start there

If you did not book directly at the rental desk, you have two counterparties and not one. And the second, the platform, is often the faster: it is frequently established in your own country, it answers in your language, it brings volume to the rental company, and when it is a registered travel agency it comes under a free ombudsman that the foreign rental company does not have.

Should you write to the rental company or to the platform?

To both, and to the platform first if your dispute is about what was sold to you online. Insurance forced on you at the desk when the platform had already sold you cover, an amount different from the one advertised, a car that was not available: those are its own commitments. Damage, deposit and fuel are settled first with the rental company, which holds the inspection reports. Both routes are free, independent, and run in parallel.

Three rules before writing

What gets a complaint sent back

01

Two references, never one

The platform's number is almost never the rental company's. On a real file, the platform wrote CG611462983 while the rental agreement carried 5858484 and a third internal reference. A complaint opened with the wrong number is returned without examination: quote both, and say which is which.

02

The written channel they impose

Many platforms refuse email for an existing booking and only accept their own form or support desk. This is not administrative detail: it is the only channel that opens a dated request. Note the ticket number and keep a copy of what you wrote, screenshot included.

03

The date of the written complaint

It is what starts the period after which an ombudsman can be approached, often sixty days. Without a provable date you cannot move to the next step, even months later.

The verified platforms

What we read ourselves

We only publish a platform's details and remedies once we have taken them from its own terms. Two are, to date. For the others the method above applies as it stands, and your details are on your booking confirmation.

BSP Réservations, France.

Rentalcars.com

Booking.com Transport Limited, Royaume-Uni.

The other platforms we recognise

They are offered when you file a case, and the portal adapts your letters accordingly. We simply have not yet verified their legal details at source, so we publish none.
