A disappointed grieving daughter, old mutual does not care and can't keep their promises

i made a clame the 01/04/2022 for my father's retirement fund however i have not gotten a response i go to the branch and know assists me they tell me to wait for sms that never comes through. I have been waiting for months and i have emailed and complained however they keep telling me that they will investigate and get back to me and know one has gotten back to me i am very disappointed by the service old mutual is giving people.
