Poor Service

My wife and I have recently bought a house. I have ordered a fibre package from Webafrica. There is already a Vumatel box in the house. Now I cannot get Webafrica to give me a new router and access to the line. They keep going on about the previuos owners ISP still being active on the line despite the fact that Vumatel has confirmed that the line has been recycled and is available for us to. I am very Webafrica and would not recommend them to anybody.
