Bad service from Webafrica and Vumatel

I am having major issues with Webafrica. They can't seem to fix the issue with Vumatel and I can't speak to Vumatel myself. They sent me a username and password on the 27th November 2020 then they cancelled my WiFi on the 30th November for non payment but both my accounts had money in it but they never debited my account. I have been contacting them everyday to reactivate but nothing is happening. I work from home and I've had to purchase almost R5000 in data. They re-placed the order on the 4th December and said I would receive an email in 2 days then I would need to make payment. No email, then they placed another order on the 4th January 2021, still nothing. Webafrica says that they don't know what the problem is and that Vumatel needs to sort it out but no one is calling me back. I can't cancel, so I'm held to ransom because if I cancel in the 1st 12 months then I am liable for the installation fees. What am I to do, my salary is cut so I can't afford these exorbitant data costs.
