Complaint Review: Radius Central Inc

Radius Central Inc offer me a position as a mystery shopper.  The emailed me several times with information they needed.  Thomas Moore was my contact person.  I was sent a cashier check for $2980 which was to be deposited in my bank account.  I need to go to the US post office and purchase 3 money orders each for $850 and a book of 10 stamps for $98.  I was to keep $250 dollars for shopping and also complete an assessment form.

I call Capital One bank and gave them the cashier check number and was told the check was fraudlent.

Thanks
