poor service

I opened a life cover with old mutual last year. everything was finalized and in January 2021 I received my contract. when I went through the contract I realised that one of the beneficiaries is not the person that I nominated. I immediately called old mutual and they indicated that everything will be updated. on the 5th January 2021 I called old mutual to check if my beneficiaries were updated. only to find out that nothing was done. I asked the agent to change the beneficiaries and he indicated that he will change. on Friday 29 January 2021, I called old mutual again only to find out that nothing has been changed. The lady who assisted me told me that she is updating my beneficiaries. when I called again today 01 February 2021, nothing has been done. What is so difficult in updating beneficiaries. does old mutual wants me to die so that they can give my money to a beneficiary that I did not nominate. I regret taking this policy as it is giving me problems and frustrating me. I am wasting my airtime every time calling *********** consultants who knows nothing about updating information.
