No internet for 4 months

I ordered the FTTH during the black Friday last year. The courier company they used lost my router. I wouldn't get it until late in december. They took another month to arrange with Vumatel to install a line. From the day of installation till now. The internet has only worked for 1day. I still get sent a bill every end of the month. I have spent a ridiculous amount of time and money calling after VOX. When they send their technicians this VOX says it's a Vumatel issue and vice-versa. I had total of 5 technicians come to "fix" the issue. I wanted to cancel the fibre. Bu I was told I would have to Pay a R2000 cancelation fee. Which makes no sense since I have not the service because the company failed to fix my fibre.
