I have received several call also. I finally picked up as I have an ill friend in the medical center in Kingsport, TN and they said I had a chance to win $25,000. Then they ask you to take a survey then they transfer you and of course want a card number! They said it was the Daily Jack Pot that I would be entered to win, and I would receive $250 in gift cards, but I don't believe they have anything to do with any of it, I think it's a scam! Also even though it was transferred it sounded like 2 women not 4(the number of times transferred)
