HDFC Bank — HDFC Bank account is locked

Address: Branch: CHANDAUSI HDFC BANK LTD AZAD ROAD, NEAR BUS STAND CHANDAUSI UTTAR PRADESH 202412

There was a upi transaction in my bank account which failed because HDFC SERVERS WERE DOWN that day (no customer fault here)
But HDFC found the transaction to be suspicious and blocked my account. So now my hdfc a/c is locked, Debit card is blocked, net banking is blocked.

I visited bank to enable my account and net banking. They asked me to fill a form. I did. As per them i will get it activated in 1-2 days and its been 4-5 days but my account is still blocked and no update at all from bank's side.

Due to this my salary wont be deposited, mutual fund sips will trigger to the account and bank will not allow to do the transaction.
Now who is responsible? I
