I rented a car from Rentalcars.com and had to prepay $250.00. I initially reserved the car for 4 days, but due to a blizzard in Chicago (where I had a connecting flight), had to change my return flight and return the rental car 1 day early. I contacted Rentalcars.com to request a refund and they informed me that I must contact Fox Rent A Car -- the dealer at Austin-Bergstrom International Airport -- where I picked up the car. I contacted Fox Rent A Car and they informed me that I must contact Rentalcars.com. I phoned each of them twice and asked to speak to a supervisor, etc. I was informed by Rentalcars.com that I must file a claim, which I did. They refused to refund/credit me. Fox Rent A Car actually charged me an early return fee, which after a couple of phone calls, they refunded. I am attaching documents to support my claim and indicating that I did indeed reserve and pay for 4 days and returned 1 day early, and their refusal to refund/credit me.
