Very Bad Treatment

We were provided GPS that has Latin language in Miami and we had hard times to turn it to English, the lady at the counter didn’t replace it and didn’t assist in changing the language for us Before providing the GPS they didn’t check if it’s in good condition or not, and on the way to Orlando we found it not working which caused us a huge delay as we got lost on the way and we had to use our mobiles to track our way to Orlando while we are being in a foreign country In Orlando we were over charged for fuel charges while having in mind we returned the car in FULL fuel, and they charged us for the GPS while we were informing the gentleman it was not working We were late for our flight and the office guy kept delaying us and asking us to pay for the fuel and the GPS despite what we were telling them to check in-front of us, and then they asked us to go look for the manager in another building instead of calling him for us!
