Lack of feedback to resolve fiber installation

I took out a Fiber deal with Vox I recieved d a mail from vumatel stating that the fiber installation was complete when I called Vox they say that on the system it shows that the object number belongs to another ISP and I must contact Vumatel so I called Vumatel and they say that the object number was given to MWEB i must contact MWEB so someeone messed up here and now i have to call these ISP's and they don't want to resolve the issue as I am a new client toVOX so VOX should resolve this and I should not be running arround to get this resolved. Please can someone from Vox take accountability for this and fix it
