Kotak Mahindra Bank — reversal of aqb maintenance charges

Kotak bank relationship manager told me that they're opening up a lifetime zero balance current account but after a year i got charged the aqb non-maintenance fees of ~rs 6000 for consecutive 2 quarters w/o any information from the bank side.

Initially, i didn't kept the funds in my account as i was unaware of the aqb & created a fd of the amount but team didn't even bothered to inform me that i'll be charged for not maintaining the aqb & not even told me once it was charged for 1 quarter.

I want the reversal of the charges as i've deposited the amount couples of months back to maintain aqb once i came to know.
