I was called on my home phone and informed I am one of the Top winner on the sweepstake and the next step is to get the "green card" from Walmart and will be instructed on procedure. I felt this is a beginning of a SCAM
This is a phone scam. They represent themselves as Publisher's Clearing House claiming you won millions, but need to come up with several hundred on a prepaid debit card for taxes. DO NOT give them any information or money. Simply advise them you are reporting the call to the police.
