ICICI Bank
Refusal to close Bank Account

I have an ICICI Bank savings account. The account has been nearly dormant for over a year now. Now that I wish to close the account, the bank tells me that I need to clear the debit balance which has been generated in the account. At the time of the account the opening, I had been clearly told that the account is a zero balance account. The account opening officers name is Mr Bagaria, who used to work with ICICI Bank Nepean Sea Road branch. If you expect me to clear the negative balance, please show me any of the correspondence made by the bank stating that my account has in sufficient funds and I have been charged a penalty for the same. There have been no statements sent to me over the past 1 year or more. Also, when I personally visited the branch the manager told me, he shall check and revert to me for the closure, but no action has been taken on that front. Now they expect me to pay the debit balance and then only are the willing to close the account. Please advice
