No feedback :(

I moved to Fourways in July and app**** to have my line moved and installed at my new place. The line could not be installed immediately because there were no available ports but the technicians put a note on my account saying the estimated date of installation would be 3 September. 3 September came and went and I have been calling every week to find out the status of my order and to see if there is a new estimated installation date. No feedback at all. Last time I called I was told I would receive a call from the technicians to explain the problem further and to see if they could provide a new installation date. Nothing yet. Can I get any sort of feedback please?
