Kotak Mahindra Bank — wrongly and uninformed deduction

Address:

1005Jaswanti gold, Mumbai City, Maharashtra, 400067

Hello sir,
My name shruti sakariyai had a salary account in kotak mahindra bank a/c i have this account for last 1 years, i left my job last year and as per policy we know that salaried account will automatically convert into savings account but it will take 3 months. Yesterday all of a sudden i received a message from kotak mahindra bank stating deduction of rs 2360 from my account without any kind of prior intimation.
1) when the salary account was opened i was told that it will be a 0 balance account (So how the non maintenance charge was deducted)
2) secondly my account balance shows amount deducted rs 590 for non maintenance on nov dec jan feb
What kind of a bank is kotak mahindra, that they charge deductions wrongfully??? That too without any prior intimation
Is this not some kind of a scam going on???
Is it not many people in this complaint board suffering from similar grievance like mine???
We seek your help. Please refund my hard earned money back immediately or else i will have to close my account and say good bye to kotak forever.
Shruti,
