Poor service

I am not happy with the service I received from Old Mutual. On the 14th of February 2023 I submitted documents for a refund, I received communication that the matter was being looked into and at some point they had an issue with the IT department but that was resolved and that a calculation was being done. After a week since that communication I didn't receive any communication as to what the status of the refund was. I went back to the branch to check, Head Office was called and they said they will investigate the matter and it would take 7 to 10 working days. The days passed and still no communication. I then went back yesterday,the 4th of April 2023 to check again. The matter was then taken to the manager to escalate it to Head Office. Today, 5 April 2023 I went to the branch and got told that I will only get a reply of the escalation next week. Now the problem is that I submitted the documents on the 14th of February 2023, it's now going into the 2nd month of no refund. I then decided to terminate the remaining policies with them, only to be told today that I will not be getting anything back, after all the premiums they were deducting from my salary(persal). With Sanlam it wasn't like this. When I terminated the funeral policies with Sanlam, I got my premiums back. Now with Old Mutual I won't be getting anything back,meaning I have lost money with them. February, March and April I still haven't received confirmation of my refund, actually there's minimal to no communication from them. I have sent emails and also went on to their website to the complaints section,only to get an automated email saying they will look into the matter and will get back to me in 5 working days. By now this matter should have resolved, I don't know what's going with them. This is not the first time they have done this to me.
