HDFC Bank — Fraud transaction in my bank account

My name is Shahzad Ahmad and bank account number is [protected]. There were four fraud transaction happened in my account on 4/9/2023 and 5/9/2023. As soon as I checked the online bank statement on 5/9/2023, I called bank customer service and raised the complaint, complaint number is MUMP[protected] and also I complained it to National Cyber Security. I am using your services since long time and did not face this type of challenge. Kindly help me in this as customer service told me that complaint has been closed. I am not happy with cuatomer service as this is the first time I have felt that you do not care for customer. When last time I talked with customer supervisor, he forgot to mute the call and said to his collegue that nothing will be happened.
