Kotak Mahindra Bank — money debited (non maintenance charges) from salary account

Address:

Hyderabad, Andhra Pradesh, 500081

I have maintained 60, 000 rs in my salary account but 1400 rs got deducted from my account by saying non maintenance charges. I asked for reversal but not credited anything. I asked to close the account at-least but they are not closing. I transferred my money to other bank account. Please close the bank account immediately or credit the deducted money. How can the bank deduct money even though i am maintaining 60k bucks in my account?? I did not receive any messages also. Close the credit card also immediately.
