Terrible customer service

A few months ago already I app**** to have my service in Pretoria moved to a new residence in witbank since I had moved residences. However this was already done on the 1st of July and still they have not installed the new line. Each time I call their call center they tell me there is some fault and they will call me back, however they never do nor does it seem like they make any attempt to solve the problem, whatever it is. Even the employees themselves can't tell me what the real problem is. I have been paying for months now for a service I don't have and they can't tell me what the cancelation fee will be either. Truely this is terrible service from a company this large. Not too mention how their call center sometimes takes 20 minutes or more to talk to someone. Truely poor service.
