Fidelity Assurance Company Secret Shoppers Secret Rip Off jericho, New York

I had went online looking for a job. Once in a while you find those secret shoppers adds and I thought that this one sounded good. I have had friends that have done this with great success but not through the Fidelity Assurance Company. I didn't think they were going to give me a position because I never got any response. In January 2012, I had finally received a letter with a check attached and instructions to do a couple specific jobs. They said to activate the check for cashing to call Andrew Young  at 1-289-892-3257 and proceed with the instructions. They wanted me to go to a Western Union and fill out a money transfer to a Sara Jones of London, England, UK in the amount of $1,480 plus $100 send fees for the Money in Minute option. They wanted me to report how my service was, how I was treated, the pace of the transaction and what not. I had to call the number back to confirm the transaction and make a copy of the receipt to verify I had done that correctly. My next task was to take $50 more of the check and go to one of the affiliated stores that they listed such as: Walmart, Kmart,Rite Aid, Kroger, Costco, Sears, The Home Depot, Office Depot or Best Buy. I was supposed to spend $50 and then once again call to confirm that I had done that and give them a full detailed report of the service I received. They told me that I was allowed to keep what ever items I purchased as a bonus for doing my job. The biggest problem with everything was the fact that the check either didn't go through or as soon as it was in my account they took it and now I owe the full amount of the check  according to my bank!!!!!!!!!!!!!!!!!!!!!!!!!! I would like to know what happened and what I can do about not owing for this!!!!!!!!!!!!
