I rent a car for 9 days as of July 31 10:00 am until August 08. I informed Rentalcars by email that I only could get the car in the morning of Aug 1st because a delay on my flights. But Rentalcars decided to fee me despite my info that I will continue with the same reservation until August 8 and had already paid for it. They fee me around US163, 00 and would refund only US$56, 00 of the amount paid of U$219. They forced me to cancel that reservation and open another one. After to refuse to cancel I had no other option, I accepted another reservation to pick up another car in Aug 1st 11:00am in Miami Beach THRIFTY agent. I had to move from Miami to Miami Beach by taxi and in a rainy day. At the THRIFTY office I was informed that THEY HAD NO CAR FOR ME. That I should wait until 01:00PM and see if they can release the car. I already paid that reservation US$188, 10. After the wait I was informed that they didn't find a car for me. I had to return back to Miami by taxi and the whole day wasted. I want to ask my rights in the Brazilian court and also hire a local lawyer in Miami to check what can I do against that company.
