Enterprise Rent-A-Car, Honolulu, HI charged $125 for new tire and $40 for gas.

My car was total during an accident so the insurance company arranged a rental car at Enterprise. I went to the nearest Enterprise and rented a 2005 Dodge Neon. The car obviously has a alignment problem since it always tilts to the right but I didn't have problem with that since I only drives about 10 miles a day. Couple days later I had a flat tire traveling to work, so I replaced the tire with the spare and returned the vehicle to them immediately, in a hurry I forgot to refill the gas. I told them that I would pay for the tire and gasoline. Couple days later they charged $40 for gasoline and $125 for a new tire onto my charge card and another $73.50 on pending for a reason they don't know. What kind of Neon needs a $40 gasoline, and a $125 tire.
