Unsatisfied policy member

On 02 November 2022 I wrote a letter to sanlam requesting them to cancel few insured members from the policy. On 15 December 2022 I received a letter that informed me that the policy had lapsed. When I enquired about the lapsed policy, Sanlam admitted to having made a mistake by cancelling the entire policy. The consultant that assisted me promised to fix the error by escalating the matter to a special team. I was later informed that the case was still under investigation when I enquired about the hold up. Fast forward 6 months later I was told that I needed to pay for the months that the policy was cancelled and I clearly refused. My reasons for refusing are merely the fact that I am not covered and have not been covered for the day the made the error so why should I be in debt for the months that they erased my policy from their books. Now they still refuse to reinstate my policy until I pay for the months that they claim are in areas which I and my family was not covered for.
