Old Mutual Insure - No responses or Updates on 9 month old case

Old Mutual leaves a lot to be desired. I've had a third party claim that's been outstanding since February this year. Everytime I've chased up, I've been met by the fact that my case has been re-assigned to someone else. I've always had to call to ask for an update and when I decided to track it daily I managed to get the person it's been re-allocated to and I was met with resistance and bordering on inappropriate responses about my case and the fact that I should chase up with someone else. I found this rather quite disturbing as I am once again trying to nurse the case to completion with yet another person.
