Axis Bank — Closure of savings Bank account

I have a 0 balance salary account at Theatre road branch, Kolkata. I lost my job . Hence whatever small amount that was left in the account was withdrawn by your bank on account of service charge. Then I visited the branch to close the account.
To my utter dismay I was told to pay Rs 315 to close the account . T
Should I be ethically or logically charged to close the 0 balance salary account by paying from my pocket when there is no job and I have not taken any amount from the bank.

I hope my issue will be resolved at the earliest
