Did I win Rupees One Lakh?

I received an envelope by post today and it offered a Rupees One Lakh cash certificate for a lucky draw I never participated. At first glance itself it was clear this offer was a hoax. The give-aways were:

1. The spelling of URGENT & no “From Address” in the envelope,
2. The Kolkata address, but you are based in Delhi,
3. The eagerness in the “Terms and Conditions” for getting your Bank, PAN & Aadhaar details.

Snapdeal has confirmed this to be not from them. For wider awareness, I am sharing this here.
