[Resolved]  HDFC Bank — hdfc bank balance hold without notice and deducted

I have been placed with a mirevenue hold through gefu negative value of 8, 000 in my savings account. Kindly explain this and remove the charges.
Hope you are doing well. This is regarding a query. My friend had opened a savings account in hdfc bank. Now the account is no longer active. I had noticed that negative charges are being levied. I also visited the home branch but was informed to close the deemat account in order to close this savings account and then pay the negative balance. As per rbi guidelines, banks should not charge for non maintenance of minimum balance. Also am unable to visit the home branch due to travelling issues. Could you please look into this and advice. My friend needs help urgently.
