Okay, I'll provide an update on my experience. As I noted a few weeks ago, Marguerite had finally responded to me that she would try to get me paid by end of last week. That did not happen...I then emailed her again. She replied immediately: "I had hoped this would be resolved last week. I have now been told that payments are scheduled to go out this week, but end of the month."
It's the last day of the month and still no response, of course. I will email her again at the end of next week. Given that they continue to schedule shops, they still clearly are in business making money, and so I plan to continue contacting them until I eventually get my money (hopefully) and never do business with them again.
I will note that I have been shopping for this company for three years. And, for what it's worth, I had to contact them for EVERY SINGLE SHOP I ever did for them, as they never once paid me on time. Every time, I would email them a few months later and they would say, "woops - sorry about that - payment has been processed." So, I really should have known better to not continue shopping for them. No other company has ever forgotten to pay me more than one time, tops.
Anyway, I will definitely keep you posted if I ever get paid. I really appreciate this thread so that I can see that I am not alone here...
