DO NOT. I repeat. DO NOT believe a word these people say. They're a bunch of fraudsters looking to scam people out of some money in exchange for a whole bunch of freebies.
Thanks for the reviews people. Got a call from a woman named Dimple promising me gifts, 1000 rupees cash back and a trip to Bangkok. Hahaha Found it hard to believe that a purchase I made at a shopping mall for such a measly amount resulted in such gifts. She didnt know my name, she couldn't tell me where I purchased specifically. Stay away from the fraudsters. They're probably scamming people into giving them money to provide them a bunch of freebies. The number they're currently using is: 080-41557065. I hope someone shuts them down!
