[Resolved]  State Bank Of India [SBI] — asking for cvv

I got a call today claiming that she is calling from sbi and was saying that she has credited shopping value of 4000 rupees to my credit card for which she needs my cvv. When i denied she started explaining me that if we share cvv also without pin no one can do any transaction on my card. I would like to request sbi to curb these kinds of fake call. I got the call from the mentioned mobile number [protected] and claiming her name as swapna.
