Packet Loss & Bad Support

My support ticket has been open since 27 May with no resolution in sight.

I work from home and my fibre line losses packets every few minutes, I have ample proof of this using PingPlotter and it feels like I've put in more effort to find the problem than them, but I can only do so much. It should be extremely rare to lose packets on a fibre line to a local server. (I have some experience in the networking field.)

They initially responded within a few days saying that it was the power supply connected to the ONU, nope. Then it was my inverter, nope. Then it was my router, nope. They eventually replaced my ONU after constant back and forth, they scheduled a day and didn't pitch, not a word or an apology, then they came a few days later. (But if you're late they charge you R500.) This did not make any difference as I told them, but when I ask for feedback I get no response.

After getting fed up, I tried Openserve, but for some reason they can't reach my apartment, I'm in the middle of Umhlanga Rocks for goodness sake. So now I'm stuck with this below average service.
