I selected a 9.00 car wash and paid 20.00...the machine gave me 2.50 in change instead of the full 11.00 I was owed. I see there have been other complaints about people being ripped off and not getting the change they were due as well. This is stealing peoples money and I will be reporting this to receive my refund. If you go to this car wash dont use them... they steal your money! I expect a return call and refund.
