ShopClues.com — getting bogus calls for shopclues

I received calls from person named vijay yadav claiming to be from shopclues.com and located at cv raman nagar, bangalore.
He informed that i have won 1st prize in lucky draw and asked me to share my account details and transfer amount of 6500 rs as gst for that prize amount.
The number from which i got call is [protected].

Please look into this issue as they might trap some innocent persons into this.
