Sorry to hear, It sounds like you are owed money as well. I was not aware that the shop did actually end early due to the client terminating the stud (I was just guessing it did). I have been doing mystery shops for 10 years and have never had payment issues until now, so it did not phase me to do a 12 month study. No notification was given to me that the study was terminated early, instead the attorney claimed I breached the contract so IPSOS does not have to pay me anything. Thanks for your feedback, I wonder how many others are owed money.
