[Resolved]  Snapdeal.com — lucky draw contest prize

I have received a letter saying i'm one of a lucky customer to win the lucky draw contest. I called the helpline number and i found something weird in their talk. They are just asking the account details without answering my queries. I found it could be fake. Please don't try to cheat people with these silly prize letters. Directly asking the bank account details is itself fake. The person sitting in helpline is bothered only about the account details. When i ask queries regarding this prize details, he was getting angry for no reason. Through that behaviour itself it was sure that they are fraud. Stop cheating people and i have lost confidence in snapdeal as well.
