HDFC Bank — credit card unauthorized transaction

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201301

I have logged the complain and fir against my credit card un-authorize transaction on 5 february 2020 this was the same day in which money was deducted from my account.
Still i have no clue about this deduction still no responsible answer from hdfc bank. The hdfc bank also add disputed amount in my next statement then i called my rm mr abhay he suggested to pay all amount. I am asking why i pay the amount while it is fault of bank.
As an aware customer i just want a answer from the bank, is there any responsibility of our data security.

Kindly assure me when my disputed amount will reverse, because i am not able to pay this amount to the bank which is not used by me. Also i was informed by my rm that my cibil will be down if i will not pay this due amount. This is responsibility of bank not the customer.

I am very old customer of hdfc bank around 10 year of relationship with bank and i am facing this type of service.
Kindly resolve this issue on priority and i am not gonna pay the disputed amount.
Credit card last 4 digit-9645
