HDFC Bank — Account blocked on 30th march due to undelivered welcome letter on 22nd November 2022

Hello Sir / Madam,
My HDFC salary account was blocked without any intimation in mail, phone or any other mode of communication due to some mailing letter that was undelivered and please note the mailing letter was undelivered in November 2022 and they blocked my account in March 2023. My salary and other mandates were hit because of this without any intimation.Suddenly on 30th March when I try to login to my account I get a message that your account is blocked and I should visit the branch
I visited the home branch on 30th March 2023 and they said they will take the biometrics and the account will get unblocked in 7 working days . After two days I went to the branch again and enquired and they said I need to go to the Vasant vihar thane hdfc branch too to get this rectified and mind you this information was given to me only after I visited the branch. This means if I had not visited the branch again they wouldn’t have informed me and the entire process would have taken I don’t know how many more days.
Moving forward, I visited their other branch ( Thane hdfc Vasant Vihar branch )as told to me and they asked me to fill the combined address form which I did and the biometrics and clearly said 7 working days.
It’s 17th April as I write to you today and the issue is still not resolved . All the helplines that I call on take me to IVR and just doesn’t met me connect to any phone banking officer. The numbers given here are outdated and it is so unprofessional on the banks side that they have not bothered to get it corrected.
Below are some of the pointers that suggest HDFC bank doesn’t care about its customers
1. They don’t intimate you before blocking your account.
2. Customer and even your relationship manager has no clue as to why the account is blocked and even if they have the clue they won’t tell u and will ask u to visit the branch.
3. What happened to HDFC’s policy about customer rights on right to information?or is it just for documentation and not in practice.
4. The branch numbers are never answered and you are clueless as to what to do next.
5. I have seen many complaints about account blocking by HDFC on this forum and I very few of them seem to be resolved.

I want a resolution from HDFC bank as soon as possible to this unnecessary dilemma that has caused me mental stress, frequent visits to their branch making me spend on my travel for no fault of mine and as they said time is money, I have ended up spending lot of time already on this. I want to know on this forum when will my account be unblocked and after doing all the necessary formalities two weeks back why haven’t my account is still blocked.
