Trustnet Financial Express Co. / Award Claim Notification

I received a Trustnet letter today, 4/12/10, Award Claim Notification from Scarborough Civic Centre, 150 Borough Dr., Scarborough, ON MIP 4N7 but the staionary indicates 4333 Charles Drive, Arlington, TX 76006. It has claim number and the instruction is to call a Lisa Greene at [protected] and I found out that area code 951 is somewhere in California. Everything about this letter looked very suspicious. Enclosed was a cashier check for $985.18 and that's suppose to be per state regulation, a tax amount of $900.00 will be required before the lump sum winning can be send to me, it states. I was going to deposit into my bank account and let it sit there to see if it will clear, if not call the B____h and tell her it's a damn scam. Or how do one report these illegal activites to the authorities?
