This was my first (and last) time doing business with Holiday Auto. I booked a car to be picked up at 8pm. When I arrived at National Car Rental with my confirmation, they had my name listed on a board for a noon reservation. They then showed me their printout from Holiday Auto, which did indeed show the car reserved for noon. Okay, mistakes happen. In this case, there were no other cars available, so the mistake meant I did not get the car I reserved, but I realized this was probably a bug in their computer program. The real problem came when I contacted Holiday Auto to request a refund. I sent copies of the confirmation they sent me and a picture of the reservation form they sent to National, clearly showing that this was their error. In spite of clear evidence of their error, they refused to give a refund. It was a small amount of money - but the lack of integrity convinces me that if they make an error over a larger amount of money, you can kiss your money, and possibly a good chunk of your travel plans, goodbye.
