ShopClues.com — lucky draw fraud

Address:

Nainital, Uttarakhand, 263139

I have received a call asking for Rs.8500-/ and claiming that I am winner of a lucky draw organised by ShopClues And have won a Mahindra XUV. I can take the car or market price of the car as I may wish.
Although I am aware that it's my responsibility to act properly in this cases.
But I m aggrieved because I am curious to know that how the fraudsters came to know my order & shipping details.
I have not believed in any of these calls but m deeply concerned about my privacy.
Kindly reply me for the matter
