Caller claimed to be calling from Sony to advise me that I had won a prize and must attend a prize drawing session at 5:45 or 7:45 tonight (or tomorrow night, or Saturday night, or whenever I am available) to claim my prize. Claimed that I had entered a contest around "Eastertime" by entering my phone number on a red and white form in a shopping mall like "Walmart, Kmart, or many other shopping malls." When I said I was not available to attend a prize drawing at any of those times, he thanked me for my time and hung up.
