They said they cant do anything from their side!
They asked me to contact the Cyber Crime Branch.
Before I do that i want to know what are the steps to follow...
Ask your bank if there's a way to unblock it.
If that's the reason there must be a protocol from their officials that if an account is found to have been connected with those reasons mentioned, they'll automatically put you in blacklist.
It's best for you to talk to the bank and ask what you should comply to unblock your account. If you have a huge amount of deposit there, ask them properly.
Since you are living in India, it will be better if you post this question in the Indian local board. People from India will better able to guide you on how to contact the cyber crime in your country.
