Kittery Car Wash

I used this car wash a few days ago. Tried to use cash, but the machine would not except my money. I tried several times, with different money, but it kept saying insert your money. Finally used a credit card for a $6 car wash. Just looked at my statement and I got charged $12. Went back there and there is no phone number anywhere to be found. Looked it up online, found a phone number, but no one ever answers the phone and no way to leave a message. What is going on with this place. Looked at the comments on Yelp. NOT GOOD!!!
