They took advantage of us not understanding English, and noted on the rental form that we chose prepaid fuel. When I questioned this, the staff claimed it was a fuel deposit for returning the car at a different location, and it would be refunded if returned full. But the bank charges showed no refund, and they overcharged by $300. No idea what the fee is! Never renting from Hertz or Thrifty again!!!! Currently trying to find out through the rental platform what the $300 charge is for.
