Vox Telecoms - Pathetic organization

Made a call to Vox on Monday morning just after 8 informing them of a problem at our business not having fiber. On Tuesday morning after numerous calls back to Vox they informed me that it shows on their side that there is no power to the vox unit I ensured them that there was and sent a photo of the black box showing a power light and an Ethernet light. Up until Tuesday no communication or update from Vox. They sent out a team of 6 technicians on Tuesday afternoon, 5 of them standing around the other one plugging out the wifi box and switching back on just to inform us, that they've sent out the wrong department and that it shows that there is a fault on the fiber line. It's Thursday today up until now at 08.00 no communication from Vox or the Frogfoot team as vox stated they gave it through to the Frogfoot department. We are losing business, can't answer calls, invoice or do our daily routine as everything is connected with the Fiber. To what length should we go to get service from the Vox service providers.
