HDFC Bank — NetBanking blocked

There was a transaction in my bank account. I called customer care about that transaction. But customer care considered it as a fraud and blocked my account. But i had called to query not to block 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 and to apply a debit card. They asked me to fill a form. I did. As per them i will get my net-banking credentials in next 7 days. Its almost 15 days and i have not received any message/mail from bank end.

Due to this my salary wont be deposited, loan emi will trigger to the account and bank will not allow to do the transaction. So will pay the penalty for that emi as well.

Now who is responsible? Is it the customer care represntive/ bank/ myself who had called them for a query
