Kotak Mahindra Bank — Close demat account

I am jitendra singh, opened salary account in kotak bank on october 2015.
Saving a/c number: [protected]
Before opening the account, kotak bank representatives given lot of good information (But really, all are fake) about the bank.
But after opened the account, i faced the following issues.

1. I have given the request to change my mail id - they took 3 months to change the mail id.
2. After 1 year, they detected rs700+ for demat charges. Actually i never ever activated and used the demat account. And i have not seen the instructions how to use demat account in kotak bank.
3. No clear idea of how the saving account linked fixed deposit interest calculation.
4. I spend half day of my working hours to give the closure request to noida sector 63 kotak branch, noida. Actually i asked to give acknowledgement for receiving the demat account closure form. They told it will not be given.
5. I forget to add one more, i have requested for kotak customer center, close demat account but not closed my demat account.

Really frustrated after facing all the issues.
Actually the above issues are very less. If collect the issues from other kotak consumers, it will be more and more.

My only request:
I want the refund of demat charges which is taken from me. Just close my kotak demat account.
Please don't waste my time and money.

Thanks
Jitendra singh
