Vodacom not assisting when fibre is down?

We app**** for vodacom fibre last week to be installed in the new apartment that we moved in on the 1st of August and the installation was only done yesterday and only worked for 2-3 hours and the internet was down. I work from home and have been missing work since Monday and now they tell us to just wait not even knowing when the technician will be sent to sort their unreliable equipment. How are we supposed to pay for the bill if i can’t work. They even failed to deliver the sim card to use while we wait for installation. This is beyond ridiculous and i am beyond frustrated right now like who doesn’t know that many people are working from home now and treat that as a matter of urgency. We actually need to cancel this contract???
