Old Mutual run around

I have put through a claim at the end of October and to date the claim has not been completed. I have made numerous calls and keep being given different explanations. Old mutual does not offer any correspondence, I have to keep calling to follow up. Huge inconvenience . Today was no exception as the call centre agent I spoke to was not very helpful or empathetic as she seemed to be frustrated with me, as if I enjoy calling everytime to follow up. After being told that status of claim is Auth to pay since the middle of December and told the same thing on 10 January 2025, today I am told that the payment was done on 30 December. This is so frustrating. I am requesting for this to be investigated as the payment never reached my account.
