[Resolved]  Kotak Mahindra Bank — service charge

My name is robin p mathew, i'm using kotak bank account from last one year. Till 2017 april my account is under corporate a/c, last month i got a message like keep minimum balance for avoid service charge, from the same day maintained minimum balance but few days ago rs 1239 debited from my account why, one bank representative information me service charge is only 450rs/month but 1239 debited from my account i need the cash back this type of activity not good for a leading bank. Please do the needful otherwise i want to close my account.
Thank you.
