Even One star won't do the justice that I encountered. About a week ago I came for a simple car wash and their self pay machine was not responding. I asked for assistance from one of the employees who was inside of the car wash and he gladly accepted to help me. I had clearly told him that I wanted the cheapest car wash( I believe $4.99) which I usually get every week. Instead the employee charged me $11. He certainly apologized and gave me a coupon for a free car wash instead of money return. I return after 4 days to redeem my coupon and the same employee said it is expired and I told him I did not know. Employee was not very enthusiastic to resolve the problem. When I told him I knew it was clearly you who accidentally charged me the wrong price he ran back without responding. What a shitty service I received for attempting to get a car wash in Scottsdale.
