I had I problem with one of their car rental companies (Thrifty) with a reservation I made on December last year. Their charging me with a car I never used because the guy at the counter didn't accepted my credit card, he did nothing to help, couldn't even cancel or make a new reservation for me. Total nightmare and now I have to pay full price for a car I didn't even used. The app itself is not bad but you have no consideration for costumer experience.
