Air Fibre down for over a week, no feedback

I took out this air fibre contract with vodacom in September 2022 and every single month since I got it, it goes off for about a good 4 days or more and I always have to contact them to get feedback, they always promise to investigate and get back to me but they never do that. I'm expected to pay the full subscription amount but they don't give me full access to what I signed up for. Like now my internet has been off since last week Tuesday and nothing is being done and I've called them so many times and I'm not getting any feedback. I wanna cancel this damn contract because I'm really really frustrated. I regret ever getting it cause I'm getting the worst service right now.
