Address: [email protected]

I have a credit card from your bank and use it properly from starting onwards.in the month of july 2020 5th. Fraudulent transactions happened to my card rs 10000/- and service charge of rs 500/- aslo. I didn't use any cash withdrawal from my cc. How come it happened. I have tried to contact your customer card but there is no proper response from the bank side. Request you to please check and find the error and reverse the fund to my card.in the meanwhile i had blocked the card for security reasons.
