Transfer of deceased estate to a competent entity

I want to transfer an estate from ABSA to a more competent entity. It took me 10 emails to just get the information from them which documents they need from me. Then 5 more emails, from which I received not 1 answer, to a specific employee. Then I laid a complaint against said employee, which she deny but I have all the unanswered emails. Now they want to conduct a telephonic interview with me, only on 2020-12-21, of which I see no relevance as I don't want ABDA t touch the estate. I want to transfer it to a competent entity. All these emals and comaints and the actual work haven't even started. In the mean time firearms get sold ollegally and things get dished out to anyonethat wants it.
