Complaint Review: USA MEGA International Sweepstakes

 I received a letter from Holden Financial Services saying I was a 2nd prize winner of the USA MEGA (under the international sweepstake) draw and that a serial number matched five lucky winning numbers, resulting in a win of $250,000.00.  They included a check in the amount of $4,700.00 to help pay for taxes. The company name on the check is The Procter & Gamble Company Shareholder Services, P.O. Box 5572 Cincinnati, OH 45201-5572 (which is the real address, I looked it up).  The check is drawn on Citibank N.A. One Penns Way New Castle, DE 19720-2408 (also a real address). I was advised to contact a claims agent by the name of Susan Page @ 1-778-862-4477. The letter is signed by a W M Hanifan it looks like, but the name under the signature is Winfred Madison, the supposed Chief Financial Officer.  I did not call this number before researching it on the internet and found it to be a scam. Beware of their changing schemes.
