HDFC Bank — Payment return fee waive off

Address:

Hdfc Bank marathalli Bangalore Karnataka

Hi team,
I have two ongoing debit card emi loan and payment for emi was made still payment return fee was charged amounting 550+99gst totally 1298 for both the accounts.
Please waive off the charges as payment is been made on due date for the accounts.
I kindly request to return and waive off the charges.
Also there was sufficient amount for the day before the end of the day and yet charges have been levied.
Please do the needful as the penalty amount is 50% of the emi and that is too much for me to bare.
Thank you.
Regards
Raj
