I have done about a dozen shops over a span of few months. They took time, but they paid for all but one. What really upset me was that I tried contacting them through their contact link twice and got no answer.
The shop was supposed to be a drive-thru teller shop. When I got to the branch, it did not have a drive-thru, so I just did a regular teller shop. I suspect that was the reason I wasn't paid, so I decided to let it go and take a loss on this shop. But what really bothers me is getting no answers. I just hate it when you send an e-mail to them and it gets ignored!
