Vodacom and there pathetic service or non service

I have since October app**** for fiber…. Vodacom has made a calamity of errors…. They claimed to connect me…. But did not do so…. They connected my line to my landlords ONT…. The staff are *********** so I called vuma who confirmed that the MAC address of my router is not connected to my ONT…. Needing internet to work from home…. I made alternative arrangements…. I do not wish to have internet with Vodacom who now request I pay over R3000 to cancel a service I’ve never to date had. And to make matters worse they’re billing me now monthly but my internet service has never been used…. I’ve had so many problems with this company honestly I have been a customer of there’s for over a decade but really I am done with them…. Their service is ridiculous…. How can it be legal to charge for a service not rendered? That’s borderline theft
