Late estate harassment

My dad passed away on the 7th of August 2020 we went to Woolworths Springs mall to report his death and we left his death certificate and ID copy as well and I even called in a week later as I was told by the head office that he had a credit life insurance on his acc to my surprise we are still receiving calls.

Yollie called in today telling us that the acc has been handed over, I don’t know how because he had a credit life insurance on the acc

Please sort this out today I emailed documents through again to *** hope this will be sorted out Acc ***62 5185 Your service sucks and we still mourning the death of our father yet you keep on harrasing us
