Looks as though you are having the same issue as [www.mysteryshopforum.com]
It sounds as though their website is doing odd things and losing email addresses. Are you using a gmail email account?
I've only completed four or five shops for Market Force. All were retail shops except for one audit. I have never applied for a FF shop. They were constantly sending me emails, most of which were FF shops and I deleted them. Now, I tried to sign in and I get the message, "Access to the website is restricted." I requested my password and gave my email address to which they replied my email address is not on file. What's up with this?
I had the same issue with Market Force. The said they had an email of mine bounce back to them. I have a gmail account. They re-activated my account, and when I logged in I had to add my (same) email address again. I will see if I get the daily shop bulletin tomorrow...
