I was Mistery Shopper For FreemanGroup. Before I enrolled with them, I searched on internet references about their payments, and some people from a Mystery Shopper forum says they took long time to redeem the payments.
Despite the warnings, I entered, and took a reasonable 1 month payment for my job and it was fine. I worked about two times again, but the payments was taking much longer time, and my final job about June 2012 has never been payed. Nobody answers your emails, and If you make a call to any extension there are only answer machines.
So, my advice is not to work With FreemanGroup. They are having some kind of troubles and they don't give response.
