Disappointing Experience from Vodacom

I wrote a review here on HelloPeter on the 6th February about my fibre that has not been working since December 2023. The Vuma team came to my place that afternoon to check the ONT and according to them there is no fault on their side. They called the Vodacom fibre department while they were still at my place, and Vodacom promised to send someone to come and check the router. It is now a week later, and no one has come from Vodacom. No feedback from them besides endless emails and text messages that don't tell me anything but just to say there is no update on my Service Request. When I call the fibre department they keep saying they are escalating the matter. I'm really frustrated and exhausted by this. Can Vodacom release me from this contract so that I can find another service provider who can actually give me the service I need.
