Meritdirect Insurance Check for $1992 Rye Brook New York

I received this check at a time when I needed some extra help and was too excited to a "secret shopper".  I cashed the check on Friday and contacted the company for several days for my assignment. I wired $1500 to a Washington address and answered questions about  the Western Union location, agent, service anprofessional imams.  Then I was told to use the remaining $80 at Walmart and buy a clothing item, personal hygiene item, dry food item, and dish ware.  I'd did those things and never heard back. Today I go to the bank to get money to pay bills to find out that the check was returned as a fake.
