Life cover

I am frustrated with old mutual I don't know what to do any. In 2019 an old mutual advisor came to my work place and I joined a life cover and they started deducting from my salary in May 2019. In 2020 around April the same advisor phoned me saying they was something wrong with my policy but iam must not worry is not serious she will sort it out. The following month may she phoned me saying I am i aware that my policy is not active I asked why because the are deducting from my salary. She told me that she made a mistake she mixed my contract with someone details. Iam a beneficiary at that person policy and the person canceled the policy they is nothing she can do I must start my policy afresh and I won't get the premiums back. I went to old mutual at festival mall in June 2020 the was an advisor that helped me and he phoned the head office they said they will resolve the problem within three month and June 2020 they stopped deducting. When I asked what is happening with my policy still they haven't resolve it and the admit that it was not my fault it is their fault and they will fix it. The advisor at festival mall send an email to his manager to escalate it to the head office to make a decision. My problem is they is no one from head office giving me feedback or to the advisor that is helping me. It's more than 5 months with no feedback i really need help when I phone old mutual with the number the advisor gave me they phone is not answered. I don't know what to do anymore.
