I made an online reservation for a car rental as part of my trip over the holidays. I paid for the rental in full at the time of my reservation. However, when I tried to pick up my car rental, the Avis customer service representative would not let me rent the car, though I had proof of my reservation. She claimed that Avis wouldn't allow me to use a debit card though I provided her with a debit card that can be run as credit. Furthermore, Avis' own rental terms and conditions state that a debit card may be used. After my trip, I spent weeks getting the run-around from Avis customer service as I tried to get a refund. I still have not received a refund for this service that I already paid for. My entire experience with this company was less than professional.
