Do you think that might be why the MSC ask for a physical description of you in your profile (height, weight, eye color, hair color, glasses, ethnicity)? So they can check it against a "recognized shopper" claim?
I agree, it sucks that they cancelled the shop after the fact.
I have only done a few shops for Mystique, but they did right by me. <----- That sounds so funny. They were fair and paid in a timely manner. For one round of shops, I started immediately, on the first available day to do the shops in the time period. I completed several, when I received an email saying to delay the shops. I emailed or called, I don't remember which, and the scheduler replied back to me that they would honor my shops since I had, in good faith with then current instructions, proceeded. They asked me to hold off on any other shops until an issue was resolved with the client. They did pay me for the ones done.
