Bad service Nedbank and Legatus Trust

My mom passed away two years ago this month. She had appointed nedbank as the executor. Nedbank handed the estate over to Legatus Trust. It has taken two years and the estate is still not finalised. Neo Makoea does not even respond to my emails anymore. I am not sure even where to go anymore to finalize it. I just need to close this sad time but every time I follow up it opens it up again.
