Vumatel on the way down

Vumatel is working on cables in our suburb. Yesterday I asked them if they will cut our signal today. They ensured me they won't. This morning they did. Now my wife can't lecture online today. If they said that they will cut us off, we could have made alternative arrangements. I have been trying to call them but can't get through. And there is no head office number. The call centre has given me three incorrect numbers. Pathetic service of a company on the way down!
