HelloD
I have a saving account in your bank account no. [protected]in the name of abitha kujalambal. I have checked my account statement, you have been charged lots of charges from my account. Why you charged .but i did not maintain sufficient balance in last two months. I have been charged ACH Debit Return Charges of Rs 236/- in June 2021.
I have never been informed that this would be charged due to lack of funds, What are these charges for?
I have classic group account but my account has been removed sudeenly I report to the bank.they ask me to sign the documents and said I will add the account in classic group. I don’t get any information from your bank .then this month and the next month the amount have been charged
RBI guidance 3 months relief COVID 19 and this really rubbish bank, my situation is very low till time and i am not pay these charges.
And Also you have been charged AMB debit return charges of Rs 236 for July 2021 and I will not pay these all charges. Please refund these all charges.
HDFC bank has to return this money. There was no intimation from the bank on the consequences of not keeping sufficient balance in account. I HAVE NEARLY 10 ACCOUNTS FROM MY SIDE I CLOSE THE ALL ACCOUNTS

Please help me resolve this. People are losing trust in public banks and these banks also. Although it does not make a difference to HDFC bank for sure, but i will close my account if it not returned. If auto debiting is a service you provide as a bank, then it is your duty to inform me on the charges for the same.
Please please help me resolve this and return my money.
