Dennis Beckett Mystery Shopper  I am truly hurt. Marietta Georgia

Dennis Beckett contacted me through my email saying that he was a group regional Instructor from within the USA.Henceforth. He said it was a job offer and I would basically act as a mystery shopper. Dennis Beckett sent me a check in the amount of $1680 and said that I should deposit it in my account and keep $200 for myself for commission, and wire $1350 to Timothy Ayew, the next mystery shopper. He first told me to wire the money through money gram at my local Walmart. He said that I am to pay attention to the area, the customer service, the length of time it took to get service, etc. It sounded legit the first time. I cashed the first check through my bank June 30th. The next day I go to my local Walmart and wire the money as the assignment said to Timothy Ayew 3015 Haverford Ln Marietta Georgia 30067. Dennis sent me a survey with questions to answer and return about my experience as a secret shopper. About two days later, he sent me another check for the same amount, $1680. He sent me to wire it at a check advance place near me. This time my bank held the check for two days because it was a high amount within a few days from each other. I inform Dennis that it was not going to be available till Monday. He was very persistent about me getting it done that day, but I couldn't do anything until Monday. I called my bank today to see if the check cleared, and they told me it did not, and the check was no good, so I got a return check fee charge. My bank called me bank and told me that the first check I deposit on the 30th was returned, so I now owe my bank $1680 + the return check fee. I just got out the hospital not to long ago and have been off work for two weeks. I am playing catch up with my bills, car note, etc, and now to face to this enormous bill. I pray that Dennis Beckett is caught for his fraudulent activities cause this right here is down right wrong.
