Supersonic fibre internet down for 5 days

My Supersonic fibre stopped working 5 days ago. After numerous calls and whatsapp messages, I was informed that the problem is with Vuma. Since then I've been promised that Vuma will send someone to come fix my fibre box. Everytime I make a query, I'm told Vuma is sending a technician. It's been 5 days without internet, 3 days waiting for Vuma tech. It's month end and they're going to debit the full amount. I'm working from home and rely on the internet.
