No internet connection

I have been without internet access since after 09h00am yesterday. My wife works from home so it has now become an inconvenience for her. I called Supersonic yesterday and gave the details of the router and the fibre box. It seems as if it could be an issue with the fibre box. As usual, they log a ticket and gave me a reference number. I was advised that they would try and resolve this remotely. The TAT apparently is 24-72 hours as I was advised. Soi I called today, and it's still not resolved, neither can anyone tell me if they need to come out because I will be able to avail myself. How do they expect a person to work from home without any internet. They don't call, I have to always call Supersonic and believe me, you hold on for over 10 minutes. This is totally unacceptable. Am I going for another day without any internet again???
