Telkom fibre peak hour throttling

I have now been battling for months with throttling during peaks hours with my FTTH through Telkom and Vumatel. Friends literally staying 2 roads from me are on Mweb and Vumatel and have no issues with degraded speeds and latency during peak hours. A friend on Telkom and Vumatel in a completely different area to me is having the same issues. I have sent technical staff traceroutes, pings and eventually was told to "upgrade" as I was supposedly on a lite package. I see my speed has been updated to the new package and yet even though I should be on a "premium" package now, I'm still getting the same issues between 6pm - 11pm. Work, streaming, and gaming becomes near impossible at times when you are getting speeds <1Mbps on a 20Mbps line, pings of 90 - 200 at times and packet loss. At a time when this is of utmost importance given we are all working from home I find it unacceptable that I can't get a straight answer for this. Call centre just continuously put me on hold when explaining the issue or worse put the call down. Sales are unable to help other than trying to get me to upgrade for no apparent reason it seems(Because this didn't help the problem at all).
