Second policy implemented in my name using my persal number without my knowledge.

I have been cancelling my policy with sanlam since last year October and they continue to deduct money from my account. Eventually they refunded me. Fast forward, they now implemented a new policy that I have no idea about and they have been deducting money from my persal since January. I notified them of these for months, they say they will attend to my complain latest 25th of May but they continue to deduct money for my persal. I want all the monies taken from me without my knowledge back because I knew that I only had one policy with them. I tried to be civil with them through the months but I keep on getting brush offs.
