VodacomFibrr nightmare

I had the worst experience of my life when I subscribed to Vodacom Fibre. I have not been able to access internet through WiFi since the 6th of December 2018. I have logged requests over and over again and all they do is close them without resolving the problem. I even tried logging a complaint on their Twitter and Facebook accounts, all they tell me is that they re resolving it. I would have canceled the service but I can’t go to Mtn or Cell C because my complex is contracted to them. I don’t know what to do now.
