Cell C, C-Fiber Worst Fiber provider in Africa

I installed C-Fiber at home 100/50Mbps line speed. All was seemed to have worked fine until Saturday 8 Sept 2018. Download and upload speeds of 0.8Mbps. I phoned support 08/09/2018 at 10h50 - Where i was told that they sending it to the back office and 2-4 hours for them to check what the problem is, i phoned again at 17h00 where again i was told its going to the back office 2-4 hours and finally got a reference number. Phoned support again 09/09/2018 11h40 - Where i was told that the C-Fiber people are not working and that the normal response time is 4-6 hours and they will escalate the problem for first thing Monday morning. Up until today i have had no communication from them in any form.

My 100/50Mbps fiber is running at 30/10Mbps yet they still expect me to pay for a 100/50Mbps line.
