Vox & Vumatel bad service

Fibre line was deactivated by vumatel by mistake. Phoning vox is a absolute mission as you stay on the phone waiting for an agent for hours, just to get an answer saying they will investigate. Still no success from vox instructing vumatel to activate fibre again. Not happy with the service from the biggest layer 2 provider in SA and one of the biggest ISP's in SA.
