HDFC Bank — Debit on my account

Last five years I am using HDFC account till date but yesterday when I open my net banking and checked the balance it shows negative. I was shocked to see that form 4th april 2023 onwards they were deducting Rs. 590 to Rs. 690 and they mention the reason "ACH Debit Return Charges" on daily basis to till date.
Even Though I am not having any loans in any bank i was deducted this month and my account details are as follows;

Account No - [protected]
Branch - ITC Centre, Chennai

I have visited the home branch and given a return complaints regarding the above issues. But the response and feedback provided by them is not satisfactory.

Please take immediate action against the issue and reimburse my money which was deducted wrongly and do the needful at the earliest.
