Absa Trustees Ignoring correspondences and or attempts to liase with them.

It is almost a month now that I have Asked Absa trust administrators to make contact with me or the beneficiary. The beneficiary has submitted a request and she has been ignored. I have asked several times on email why I am being ignored. To date no response it seems the emails literally are not answered,calls not answered either. Their 4 to 7 working day rule to respond has gone way beyond that being a month now.. I have asked this on email as well but to date I have not received a response. Then higher management wants to say things such as I run to social media. So please advise what does one stand to do when no authority figure nor trustee,nor administrator answers emails. And this the administrator appointed to the file is the one ignoring correspondence as well as the administrator the seniors, the trustees.
