Survey Source Services Fake Check Fraud London, Other

 I received a check in the mail from Servey Sources Services and was instructed to contact a S. Brown he insisted I cash the check and call him back...lol.. I am no fool though the check looks good it is drawn from a Bank named Silicon Valley Bank, with the account holder being a long term corp. of QLogic. The envelope that it came in was stated personal & confidential, it had the Home Depot logo in uppper left corner, also in the envelope with the check were instruction and on reverse of instructions was a survey report for western union, walmart or costco, and Sears or KMart. If you cash the check you will be asked to send all but three hundered to a spwcific name via Western Union and once the bank figures the check is bad it is too late as if you had you used the money you will be rsponsible to repay your bank.
