HDFC Bank — Submit account closure form by visiting the hdfc bank but account is active and debited with non maintenance charges

I have submited account closure form by visiting the hdfc bank phase 3B2 Mohali branch and paid all previous due. but account is not still not closed and account is debited with non maintenance charges of Rs. 600 + GST for NOV 2022. I did not done any activity in my account after submit account closure form.

I have got this email from bank:
We would like to inform you that your account no xxx0732 is debited with non maintenance charges of Rs. 600 + GST as you have not maintained the required balance in your captioned account for NOV 2022.

it is horrible and shocking for me. i cannot expect this kind of irresponsble behaviour from a reputed bank.

please remove this charge and close my account with zero balance. please do not close account with negative balance because i have paid previous due before submiting the account closure request. it is bank responsibilty to close my account becuase i have submited account closure form.
