who was the message from? What did you do to win that money? Did you enter a contest?
Its probably a scam. They'll ask you to pay taxes in advance, keep that money and never send you the prize. Or they'll ask for your credit card number "for identification" and use the card to buy stuff for themselves. Or they'll ask for your bank account number so they can "deposit the proze" and empty the account instead.
CONGRATS 943******* has won $3000 Cash prize, call +2392879006 now.--- that was the SMS I received on 16 th Mar 2011, 7.35 PM. I have the habit of receiving such SMSes all the time,but the prizes fail to reach me. Why don't the legal authorities catch and try them for misleading and swindling the people !! Know what??.. Even the legal companies are adopting the same procedure to lure the common people to push sale their policies/products etc, by randomly calling and selecting the mobile nos.,eventually for their own profitable ends.
