Today at approx.9am, a person was getting money out of the changer and noticed I pulled into the next automatic lane. She asked if it was working and told her my five would not work. I was behind one car washing. It took my money $6 but no car wash. She took her money and ran. There was no posted numbers for problemss. I looked it up on tne internet and tried the number given. No answer - I will keep trying to get a refund. It was a waste of time , money and poor management! smm
