Complaint Review: quality consumer research

I recieved a letter with a check in the mail,stating that i was going to do a customer service evaluation at a western union.I needed to call the company and get the information where to send a amount of money and that when i was finished i would have to do a survey on how easy it was to fill out paper work and how well the service was at that western union.I recieved a check on $980 dollars and was to make 150 making 75 per hour.then i was to send 750 to a andrew thompson in canada.I went to my bank and did as requested and also to western union and sent the money.Little to my knowledge i had to go to my bank today and the check was no good!i also called the bank on which the check was written which was finance center federal credit union out of indiana.So now my savings and checking has been drained and i still owe the bank 87dollars.I have been scammed and dont know what i can do.My bank says even though the check looked legit and they cashed it that i was responsibly.Please anyone who recieves checks from this company do not do what they ask or you will also be out your own hard earned money.Someone please help us fix this problem.
