Kotak Mahindra Bank — poor service and false information

Address:

133001

One of the representative told me that the new account will be operational in 5-6 days. It has been 25 days now and i have still not made any transaction. They have locked in rs11000 of mine and i can't make payment for my credit card bill and have to incur interest on late payment. They charged me rs750 for demat opening without telling me any such charge.
I have tried every mean but the response rate of their customer care is terrible.
Only account is open i don't have any debit card or net banking password so what's the use.
