Standard Bank cancelling 45 year old paid Funeral Cover Policy without consent of policy holder!!!!

I'm trying to assist my 83 year old father who is with Standard Bank for almost 50 years. He as a funeral cover at Standard Bank that he took out plus minus 45 years ago. He took out funeral cover for my brother but he wanted to cancel the policy and contacted Standard Bank last Friday, but was informed that he can not cancel the policy as my brother needs to cancel it himself. Monday he phoned again and was told that Standard Bank assumed that he wanted to cancel his own policy that he has paid for the past 45 years, so they cancelled his funeral cover policy!!! He did not give them any instructions to cancel his own funeral cover policy, I mean who will cancel a policy that he paid every month for the past 45 years. They then told him that there must be an investigation now, there is no time for investigating Standard Bank's own stupidity. HE IS 83!!!!! Anything can happen and now he doesn't have funeral cover. There is no time for investigating, Standard Bank needs to activate his funeral cover NOW!!!!!! And conveniently when you phone them he is just cut off!!! Standard Bank wake up !!! This must be rectified NOW!!!!!!!!!!!!!
