Old Mutual provides terrible service.

Me and my twin brother have policies with Old Mutual. In 2016 when our father passed away, we found out that they have mix or combined our portfolios when we were claiming. Clearly someone at Old Mutual who was capturing our details when we were joining, incorrectly captured the details. Even though our initials are the same, but our names are totally different. I was the first to join then my brother later. My brother's claim took longer to pay out due to that. We were assured that they will fix their debacle back then in 2016. To our surprise now in 2024 the matter was Not fixed. We found that out when my brother was changing his banking details. We went to the branch and logged a complaint again, that was in April this year. I have about six active policies with Old Mutual and after the branch visits the problem became worse. They debited all my policies on my brother's account and when we complained about that they only reinstated half of my policies back to my portfolio. They also mix up our details on my App in which my brother does not have one. There is a rewards program on their App in which I already accumulated a lot of points, but they are all gone now. We have sent spreadsheets to them to assist them to distinguish our portfolios but till today the matter is not sorted. We are worried now whether we will get our claims when we have to claim should anything happen.
