Fibre connectivity

I have been without fibre service for nearly a month! I have been contacting Afrihost almost every day speaking to a new person every time having to explain my issue over and over. All they say is that I must do this and that which I do. I have requested they send a technician as I am not able to solve the issue as there is clearly more to just switching off and on or connecting a pc and trying to resolve the issue. Everytime Afrihost tells me my ticket was closed by Vumatel! This does not help me as I am now paying for a service I am clearly not receiving! I am at my wits end now as nobody seem to want to help me to resolve the issue!
