my11circle scam

though they don't charge a rupee for the competition they offer prizes in gold, silver, cash, motor cycles, mobiles, I phones, watches, Boat Ear phones and many other things. I won Boat Ear phones at the recently concluded IPL. It's over a month since I won. I got 3 whatsapp messages that I won and they will get back shortly. NOTHING HAS HAPPENED. There has been no reply to my query too. i It may not be a scam by the looks of it, but why fool peoplewif the prizes do not exist BUT THE PROMOTERS MAKE A LOT OF MONEY ON THE MANY ADVERTISEMENTS.
