Line cut for no reason even unknown to Vodacom

I have not had fibre connection for 2 weeks, Octotel a provider of Vodacom came to cut my line for reasons unknown to myself and Vodacom. Surely they should hold their vendor accountable but between the two they are useless. I asked that someone come to my home (after they did come a week back and said all was working only for there to still be an issue). I work from home and had to spend a small fortune on data this past 2 weeks and as things get busy as people return to work I have still not received a response or ETA. When I asked if I can cancel my line I was told there would be a notice period… from what… notice so I can get charged but there is no internet???? I’m really frustrated
