Old mutual life policy

I am highly disappointed with the service I have received from the Old mutual life policy group, my mom passed away 6 months ago i have provided all the relevant information regarding the claim but till this date I have received no constructive feedback , the claim has been with the assesors for months now! How long could it possibly take to get information from one clinic?? this is emotionally draining dealing with the death of my mom and having to go back and forth with this claim just makes it harder!
