Old Mutual haven’t paid my mother’s retirement annuity after a claim was done 12 months ago!

I lost my mother 18 November 2020 , her old mutual policies we processed a claim a week later after her passing, it’s been a year Old Mutual hasn’t given us any feedback regards to her retirement annuity, it’s unfair while we still grieving and ills mutual has delayed while my mom was paying every month, when we got into the branch worse service ever and this matter is not resolved, , what kind of service that allows a grieving family to keep on chasing them after a year! Zero feedback nor accountability! You could swear we asking for a loan we only want what’s due to us as a family! This is cruel and Inhumane to ignore someone while they are at their vurnable state ! I demand a resolution ASAP.
