Vumatel - ***********, unable to resolve problem

We relocated over five months ago and have been trying to get our new configuration settings from Vumatel for our internet fibre connection. Our deal is part of a joint Vodacom/Vumatel installation and so we have to go through the Vodacom centre. Vodacom has been as helpful as possible, but Vumatel are unable to resolve our issue. They say they can't find our line, and have no sense of urgency for this to be fixed. It is now 150 days that our complaint has been open and they simply display arrogance - to us and the Vodacom employees trying to resolve this issue. Vodacom has now suggested we begin the installation from scratch. Vumatel are quick to take on board clients but there's no way to get this issue fixed!!!!
