Worse customer and fibre services

I have had this USELESS fibre not working for 4 days now. Now it makes sense why they opted not to have a contact centre and they knew that their services is appalling and degrading to use, and they didn't want us to voice our complaints over their agents. Now i have been speaking to 3 people regarding the fibre not working all promising to the escalate to a technical and still no technician came through to fix or check where the problem is. So now my request is simple cancel this nugatory system with immediate effect not interested in anything or extenuate further. Just execute my request so i can find a better company that will merit to give desirability service.
