Mike you are so right. I have always been paid when I complete the assignment as instructed. The couple of times I didn't get paid it was my fault for not reading the instructions more carefully.
CheckMark had some problems last summer with payments. Because of the boards, I knew it was going to be a while. They owed me $234 and none of it was reimbursements. I watched the boards and the horrible way shoppers behaved, which by the way did them no good. I knew either I would get paid or not whether I pestered them or not. I just waited patiently and almost 3 months later the check finally came.
The lesson I learned was to never put anymore into a company than I can afford to lose. When my money is on the line, such as reimbursements, I am especially careful to do the assignment exactly the way the company specifies.
As for for my worst experience, it usually has nothing to do with the shops. It is more computer related. For instance, last night I went to the bathroom in between reports. My little grandson got a hold of my mouse and took the little ball. I do not know how to use the computer without a mouse and the rest of my reports were due by midnight. After 45 minutes on our hands and knees, my husband, my daughter-in-law and myself found it between the refrigerator and the cupboard. Another problem he is famous for is turning of the power strip and shutting down my computer during a report.
