Bank did unauthorized debit and gave Misleading investment advice

I opened a saving account with HDFC recently The personal banker advised me regarding investment in mutual fund at the time of accounting opening, she also arranged for phone conversation to discuss basic information with the fund manager, Based on the conversation with the fund manager I was convinced and agreed to open the account. Unfortunately I trusted the banker and signed the relevant bank forms and blank customer consent form as I was to go on an urgent business trip. To my rude surprise I discovered later that the banker has sold me life insurance linked ULIP. I am NOT interested in any life insurance related product. There was no discussion regarding my life insurance need. I have two major concern: 1) My saving account was debit without my agreeing to their proposal sent through email. I have not provided my approval yet. On questioning the banker said the money has been invested in my name. Is my money safe? How can I have the money credited back to my account? 2) The investment product was not selected by me so can the bank force me and am I stuck with it? Appreciate your advice Thanks
