Sharekhan — Unable to close my account

Its been a year since I submitted my request to close my account. There was an issue and they told to resubmit the form physically. They locked my account and I am unable to login to it. To fill the form I need details which are available only when I log into the portal, as they locked my account I dont have details. I mentioned this issue an year ago, till now there is no resolution of it, I am constantly calling their customer care but no one picked my call. Their customer service is worst, they dont care about customer issue. Since 1 year they are not even trying to reply or resolve my issue. Their competitors are far better in providing service.
