prize winnings

Got a call from someone claiming to be from homeland security stating that they had intercepted a envelope from Readers Digest with a LARGE check being sent to me.  Said that I owed $2,475 to have it sent on to me.  Gave me a name of an alledged prize coordinator for Readers Digest who also told me that I would have to pay the amount.  Both were very convincing and promised to try to help me defer the charge and would call back.  In the meantime I checked with BBB and was told this was a scam.  The number I was given to call the man from Readers Digest turned out to be for Paetec Communications Inc.and I also found that this man did not work for the Digest, even though he said he did.  I also found that there was another party that had been given the very same story I had .  Right down to the same amount of money to the case number for Homeland security.  These guys are doing some shady things!
