IDBI — Non closure of account

Address:	Bangalore, Karnataka
Website:	www.idbi.com/index.asp

I had submitted the closure of account in person and in writing to the branch but i received a letter asking deposit of 300 rupees as service fees for closure of account.

1. I Never used this account not i maintained any balance since 2010.

2. Does the bank maintain the account and keep sending me zero balance account statements for eternity?

3. Does the bank wait until i deposit 300 rupees for closure of never used account?
4. I really sounds funny when the account is not closed when no transactions done not even once.
