Vumatel: worst customer service EVER

It has been more than two weeks since my order has been processed and NOTHING has happened. The line hasn't been tested as I was promised on three different occasions and also promised that I will receive a call for installation and that I will have fibre within two weeks. I have been promised by numerous employees that they will phone me back with an update and I am still waiting. I have not received ANY communication from Vumatel's side. I then phoned my service provider and get told according to Vumatel they did phone to make an appointment. So if I am busy at work, busy with clients, or for whatever reason unable to answer the phone (and it is a no-number so I can't phone back) then no-one phones you back because they tried and I didn't answer. Fed up, disappointed and frustrated. I can't even take my business elsewhere because Vumatel is the only provider in my area. I have people working from home that is losing business and money because of the incompetence of Vumatel.
