Complaint Review: U Haul Authorized Dealer

On June 30th, 2015, my mother and I came in to rent a U Haul. 19.95 plus insurance. Total came to 49.80. I wanted to pay cash but it's required that a card be submitted at drop off. We returned two hours later, and I paid cash. I remember that I gave him three 20 dollar bills because I didn't want to give him a 50.00 bill. Some places are funny about that type of thing, so I handed him smaller bills and put the 50 back in my purse. He went outside to check out the truck and acknowledged that the truck had a full tank of gas upon return. I smiled collected the receipt, and we left in my mothers car. 

Today my mom gets her AMEX statement and 45.80 is on the bill! I tell my mom to dispute the charges, but I call the store and it rolls to a customer call center who will leave a message for the manager. I have a bad feeling already, so I hang up with her and drive down to the location. A friendly and helpful Latina woman looks me up in the computer and prints out a receipt that shows I paid by credit card!!! I point at the Asian man behind the counter and inform her that I paid cash to that man on the 30th. He doesn't say anything. I know he either does this to people on purpose or maybe he made a mistake, but he doesn't care to discuss it. So I storm out letting them know that I intend to take them to court. In the meanwhile, my mother is disputing the AMEX charges. What a ripoff. 90.00 for a U Haul for 2 hours!!!
