We are having problems with our Wash Card system AGAIN. This time, the system goes down during the heat of the day. We purchased two new Unitec pay stations and had the Wash Card system installed before they were delivered. Wash Card assumes the units are getting too hot during the day and we lose our ability to accept credit cards and wash cards but they don't seem to have a fix for this. It's costing us money and no one at Wash Card seems to be able to help. They keep doing an "upgrade" but the problem still exists. I'm sure we are the ONLY ones having this problem but just in case . . .
