I'm sorry about the pizza shops not being paid. I don't do their pizza shops since the one in my area I won't patronize for political reasons. Even if I didn't have that issue, it's an extremely picky reimbursement only shop. Not worth the trouble. Anyway, about the phone shop being rejected because you were identified as a mystery shopper, since they record all of their phone shops I don't understand how that is your fault unless you made it obvious. In that case they should tell you what you said that gave you away so you don't do it again. I'd push for an explanation if I were you. Good luck.
