Useless Vumatel service

We are 3 people working from Home and are totally dependent on our Fibre network connection. Since Sunday morning we were down. Reported to Webafrica and the excuse was that the time to respond from Vuma was 48 hours during work days. Eventually Vuma came on Wednesday and found a broken fibre cable in our ceiling. Told us they will report it to their offices to send an installation team to replace the fibre cable. No matter how often we contact Webafrica the best we get is that they have escalated to Vumatel and nobody is able to give an estimated time for when we can expect the Vuma installation time. In fact, Webafrica says that they do not even receive any response from Vumatel at all.
