First and last time I use this service. I booked a car with them in Paris and paid full amount oт reservation. They convinced that the amount is final and no need to pay extra. What was a surprise when at the end of mу trip the rental company - Sixt in this case - has debited from my credit card additional money.
All attempts to contact RentalCars.com and clarify the situation were unsuccessful, the phone numbers do not work. I'm writing this review so you can be forewarned. Think twice before choosing this cheater...
