I have been mystery shopping since 1993, off and on. I started in Tucson in the 90's, then in Michigan and now in the Seattle area. Boy have I been busy. I mainly do apartment shops. I have burned twice in the last month. First was with Bestmark. They called and asked me to do a rush shop and were extending it a few days for me. It was for a casual chain restaurant. First time with them. They said they would pay up to $25 plus a tip. I said I would do it and we agreed on a certain day and I had to take a friend. I also signed up to do a car dealership. So I do the shop. Get in touch to find out why my check was so low, tip wasn't reimbursed plus they said I was late. First I call the woman who called me, and no reply. I call & talk to someone, she would check, never called back. I finally leave an email. In the meantime get a nasty email about the car dealership being late and I have already entered the info but was waiting like they said, to enter the follow-up. I left a msg, no reply. Left them a detailed email saying I would never shop with them again.
