My name is mattapalli omkar ac number [protected] i have debit card emi since last 2 years Total amount is ₹10698 and I paid ₹8800 due to my financial struggles iam unable to pay remaining amount due of only ₹1800 instead of that amount my account shows me now as per today's date[protected] it is ₹ -23000 balence this is 3rd time i raised my compliant but action is taken by hdfc bank.
I didn't receive a notice from bank regarding this negative balance even one letter also this is ridiculous .Why do they put my account on hold for negative balance.
