ICICI Bank — Account freeze since 1 month

I really regret, frustrate for having an account in icici. My account got freezed last month without any prior notice, sms, or mail. And I have visited to the bank 4 times since last month(literally a month) and the issue is still not resolved.
Every time I go they take the proofs from me saying it will be resolved in 2-3 days and it's been 1 month it's happening.

I just don't want to continue anymore with this bank.
Please return my money or resolve the issue immediately.

I rate 0/5 for ICICI bank services towards customers.
