Stressed Client due non communication/ response

I'm very disappointed. It's been more than months trying yo get through to Sanlam Beneficiary Fund, but there no response. I called, transferred from one department to the next until it disconnected. I have sent numerous emails but only the automated response. Even went via the website to request a call back but no response whatsoever. Their WhatsApp says they can't assist with this query.Truly this is totally unacceptable for an established company like this .Why have all these communication channels but not in use to assist the clients.
