Connection issues/Outages but still not getting the proper assistance

I have been struggling for weeks with this ISP. After having this Fibre installation done in September only. And everytime been referred to an Agent via WhatsApp, same troubleshooting, same rebooting the router, same reprovision of lines etc. But connection is so poor. Cannot connect to my smart box, doesn't even pick up the connection. Cellphones and things work. The last time fault was logged, it was closed about 10min later with the same ****py troubleshooting steps and I am no closer to a resolution. Been trying to call. Trying to connect via WhatsApp in the last 2 weeks and still no assistance. When checking for an outage the same outage picks up for Vuma Reach....but not once would an agent pick this up, and yet looking at the fault outages its been weeks. This cannot be the best service. I am unhappy with it. Even at the highest package I'm not finding any joy.
