Global Test Market SCAM, mail fraud, They sent a letter with a check phone no.to call.w/ an offer to evaluate the security and efficiency of retail outlets. You deposit the check, they tell you once it clears to buy th Stamford, Connecticut

I received a check and an offer of employment from Global Test Market.  They say they are looking for Customer Service Evaluators.  They said they needed evaluators looks at the customer service level of stores and providers.  

They tell you to deposit the check and once it clears to call them for further instructions.  They asked me to purchase three green money paks.  I thought I was safe as I had a cashed check.  I mailed the money paks to them as requested.  The money paks are like pay pal.  You use the cards to purchase merchandise over the internet or at specific stores. 

The check was drawn on Communitywide federal Credit Union using their routing number but a fake account.  The check came back with note on it "account Closed"

I called the bank and they said it was a scam and gave me the information about the bank.  I called the phone number given  on the back of the money paks.  They had already been used and  had zero balances. I was told to report it to the us postal inspetion dept.  They have an automated service asking if you want to be sent a form to file a complaint!
