Kotak securities are the worst investment services.first of all they do lots of formalities to open a demat account.after opening it they take lots of charges like brokeage charges, annual maintenance charges.these charges are more than other demat account company.
They customer service is very bad if you have any issues regarding anything related to demat account if you call this company's customer care service didn't even receives your call.I won't recomment this to anyone its bad service and complete waste of your valuable money.
