The caller is a fraud. If you get a call from this number, never share any of your credit card or bank details. It is a scam. Credit card companies will never ask for sensitive information like card expiry date, card number, name on your card etc... The caller says it is for verification, and if we don't share they will deduct 5000/some other amount from the card. Don't believe it is a scam to use your credit card.
