Unable to fix speed issue I am paying for 100mb line

I upgraded to 100mb line but getting speeds not more than 30mb for the most, Last night i got 20mb download and 918Kbs upload speed. this is pathetic, I have spoken to all 3 agents from webafrica and that they told me that there is an outage in Delft for more than 200 days and they not willing to come out to fix it and never will due to high risk area, poor poor poor service, its so called high risk area then why did you intall fibre in our area in the first place? they offer me to downgrade back to 20mb line but i dont want to then i will run speeds of 1mbs i am working from home and need my internet to be fast i am paying alot of money for 100mb line the cables was vandalized so i suppose if no one is willing to repair it i need a discount then end of story i am a paying customer. #Vumatel, #WebAfrica
