[Resolved]  ICICI Bank — NEGATIVE BALANCE ON SAVING ACCOUNT

My ICICI saving bank account No is[protected]. Application for closing of account is not accepted by bank branch and is showing negatve balance on account of deduction of charges for non maintence of average quarly balance.
I want to know on basis of which rule the saving bank account has been debitted and is now showing a negative balance. I HAVE NOT APPLIED FOR CREDIT LIMIT AND THIS ACCOUNT CANNOT TREATED AS A CREDIT CARD BY THE BANK.
I donot want to maintain this account and the account should be closed.
