Invalid policy

My mother passed in September 2022. I've since been liaising with Momentum to advise them of her passing and how we could continue with the policy. Momentum then required documentation from me including my banking details saying that it can continue in my moms name as is with me paying for the policy. I submitted all required and payment continued. Today I call Momentum wanting to make a change to the policy and get told that I was misadvised by the agent. The policy should've been cancelled and a new one opened on my name, also if ever you wanted to claim it would not have been possible. My heart sank and I was so terribly disappointed. How do you take my money for a policy that is actually invalid as the person passed. How do you make me go through all that trouble, and after many emails to tell me this. The incompetence. I would like my money refunded from November 2022 to date and I have since cancelled this policy. Its not okay for you to misadvise clients during their darkest times and not rectify the problem immediately after realising that your agent made a blunder. Kindly refund my money.
