Syndicate Bank — minimum balance charge while account is not in use from last 3 years

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201301

Hello sir/madam,
I have an syndicate bank account which was opened up by my previous employer. I left the job 3 year back and no transaction is don during this tenure. Though, i left inr 700/- in my account but minimum balance charge is applied to my account. Once i went to syndicate bank near my home town, they checked and told me that i have inr -2000/-. Thus i need to pay 2000 rupees to close the account. How one can be charge such an amount while he did not use their service. Even they did not intimated me via any source of communication.
Kindly help me to close the account without paying any charge as i was not aware of such charges.
