I'm a co-worker and I want to comment on this in general, not necessarily specifically with the the OP although the OP is not excluded. I don't want to argue. This is the entire two cents of my two cents on this.
Many of us have done shops that have been denied by multiple mystery shopping companies. We fail to understand, or we fail to execute flawlessly, and it happens. Sometimes the guidelines are not clear. Sometimes the guidelines are clear but we misunderstand. Sometimes we understand the guidelines perfectly and we still screw it up. Not to say the companies are perfect. Neither are we.
I have had shops rightfully denied. Others were questionable in my mind, but not to the MSP. I have been dropped from programs. Once, due to an error I made. Once, due to a mistake on the part of a scheduling company. I lived over it. I have more work than I care to do. Lots of jobs, lots of scheduling companies, lots of MSPs to work with. Provided, of course, I keep the lines of communication open and don't damage my own image.
This is not a question of who is right and who is wrong in any one case. The question is how best to handle a reputation.
Once a shop is denied, and we inquire, and it is confirmed again that the shop is denied, we need to make the best decision going forward, keeping our own future access to work in mind. Although we may decide to move away from the company refusing the report, we can do that privately without breaking the terms of the contract. Reproducing communication with the MSP is probably beyond the pale. We need to keep in mind the professional image we present to the rest of the mystery shopping community. It is in our own best interest to negotiate with courtesy and an understanding heart.
