This company is shambolic! Terrible customer service. One agent on the phone even hung up the phone on me when I asked them if I could speak to someone else. I made a booking with them for Europcar and it said in the details that the pick-up deposit must only be made with a credit card and nothing else. I called them to ask about it and they confirmed over the phone that was the case. I had to change my booking to a more expensive rental that would accept debit cards. When picking up the car the Europcar the office manager told me that they always accept debit cards and that Rentalcars were wrong. After a truly painful experience trying to get the difference refunded as it was their mistake they eventually outright refused saying it was my fault. So it was my fault that I didn't check the incorrect information when making my booking??!!! Trying to submit a complaint about a rental is almost impossible, I think they just hope you'll give up. You'll have to pay extra for the privilege of using them as 3rd party and if you have a problem they'll conveniently disappear. Just go straight to the rental company
