Mystery Shopper Evaluation Team review: Scam 1

I've received letter with check for $984 enclosed, according to the letter this money should have been used to pay taxes in order to get $100 lottery prize. I came to my bank and cashed the check, next thing I've wired that money to those scammers believing that I will get paid $100. Soon my bank called me and notified that check I've cashed earlier was fake and I have to return all the money, but thing is that I've don't have it already
