Kotak Securities — levy of charges

Before lodging complaint i wish to advise everybody dont open any demat account with kotak mahindra bank. Because they are cheating the public. I had a demat account with kotak securities client code jp6d0. My name is r. Santhi. When i opened my account initially they told us that charges will be levied for transactions done at 0.25% on each purchase and sale transaction. Due to the wrong guidance of mr. Suman executive of kotak securities i lost about rs.1.00 lakhs in tranctions. But when i want to close my account he said that my account is at a loss of rs.4.00 lacs. Some hidden charges like interest for the limit, turnover tax etc which were not advised earlier have been debited to the account. I want to go to consumer forum. I had a doubt that some of my sale transactions have been routed to the account of mr suman executive instead of my account. I request you to investigate and advise us
