[Resolved]  Snapdeal.com — reebok shoe

I have ordered a shoe and which i cancelled on 15th of december but still haven't got my refund.in 2 or 3 business days the refund money gets back usually to bank account but snapdeal team has disappointed me.
Moreover,
Today i received a call from a random man claiming he is an employee of snapdeal who wants me to register a form and give them the money of registration which is 8500. And gave me his id proof details also which seemed fake. And all this he did because i was the lucky winner whose name flashed on top of a certain list or something and i won a car and if i want it i have to register it by giving them that amount. Or else they will send me that 12 lacks cash. It just doesn't make sense.
