HDFC Bank — Account Blocked

Hello Team HDFC Bank,

On the 5th of August 2022, I received an SMS stating that my account has been restricted due to an undeliverable address after that I visited the branch and did a re-KYC and after that, my account got blocked and after a few days, I received the address change letter & took it to the bank and asked why is still my account blocked they said it will be solved but it didn't then they scanned the letter and sent it to the backend team but no response and now it has been more than weeks & my account is still blocked and due to which I'm unable to make any transactions through my account and this situation now has been more than a month. I'm really disappointed and frustrated with this service of HDFC Bank. Please help me unblock my account.

Thanks Regards
