Five disputes, every company, all across Europe
A generic complaint is dismissed in three lines. The argument that works is the one that matches your exact situation, and it is not the same from one dispute to the next.
Charged after returning the car
No, not for a period during which the vehicle was of no use to it. A trader only charges for services actually provided.
Damage charged with no inspection report
It has to prove it, and an internal tariff is not proof. The burden lies with the trader: it must show that the damage is attributable to you, when it was recorded, and what it actually cost, with a paid invoice rather than an estimate.
Fuel charged twice
No, and this is the line most people leave on the table. If a fixed fuel amount was taken at the desk and you also returned the car with fuel in the tank, that is two payments for the same litres.
Insurance forced at the counter
Consent obtained that way is not free consent. Cover sold at the desk is an additional service.
