[Resolved]  Snapdeal.com — Lucky draw winner

I received a speed post today with scratch card and a certificate that says I am one of the winners. It has my name phone number and address on it... Saying I am one of the winners and have won around 7 lakh rupees.. tell me is it genuine or not because I smell something wrong here.. and even if it is wrong then Snapdeal should take measures to keep our information personal and take action against such fraudulent going on
