I too received a check totaling $4,510.25 # 106603 the check was so authentic that for a minute there I thought I was a winner.  Once I read on I got suspicious since they ask that I pay a fee of $2,200.00 and since I know that if I win I should not have to pay anything other than the federal taxes. I then started doing some research and I am glad I did. I then rip up the check and trash it. This scam had to be stop some how.
I am reporting this hoping to help someone else that may receive similar letter.

I didn't get a call, I got an authentic looking check in the US mail on July 1, 2013, payee name is  Repocast.com Inc 601 Gordon Industrial Court Bryon Center,MI 49315  for the $4,510.25.

I Checked with the bank drawn on and they confirmed that it was drawn on an open account, with sufficient funds to cover the check. But of course they could not verify that it was not a counterfeit . The return address on the envelope that the check was sent in was from Canada, as was the phone number 1-778-779-2299, contact person Tony Ellis, transfer agent Ann Lewis.. This is a total scam. Cash the check, send the money and you'll get stuck for both the amount paid and the bounced check fee.

I got this letter and check for 4,510.25 was ask to call them at 1-778-779-2299 before I cashed the check and   pay 2,200.00 . Iam glade i checked on the internet first . thanks so much..

Thanks for the reply.  Was not going to pursue it.  Was not even on original stationary.  It was a copy.  I agree, but how do we stop them other than not falling for it?

Come on people, the scam is simple, you put the check in your bank, send the tax collector the $2000. The check bounces, you are out the money from the check, plus the money you send to the "tax collector" and your bank charges you for the bad check you cashed, total over $6000... YOU LOSE! We have to stop these people from taking advantage of those that are hoping its all real.

Got the same letter as you June 25th and really need it but that's my luck, IT's probably A SCAM

Got a final claim notification for winning a sweepstakes.  This is the only phone number on it.  When I goggled Michelle Stafford's name, she came up on another link to this site about a scam. Some other names on the letter are Keith Otis who is claim agent to be contacted and Wendy Larson tax agent.  The letter head is AMEX FINANCIAL SERVICES 4840 Cactus Avenue, Las Vegas, NV, 89141.  What is the scam?
