Kotak Mahindra Bank — Wrong Information and guidance to make me open an account

Address:

Leela Arcade, beside SWEET HOME, City Light Town, Surat, Gujarat 395007

Respected sir,
I wanted to open Kotak 811 account which is completely free with zero minimum balance but one of the sales executives of Kotak Mahindra Bank City Light branch surat assured me that if I keep my minimum balance for 6 months of amount 10, 000/- Rs then later on my account will be updated to a minimum balance of zero with the same services I am being benefited as Kotak Saving Account. But now even after 7-8 months, I am not benefitting any of the promising services even I needed to keep my balance up to 10, 000/- for a whole year but I had withdrawn my amount so I am here to request you for the same so Kotak won't charge me any of minimum balance or any unreliable charges.
Following are my Bank details :
