Waiting for Telkom to install land line

I requested for Telkom to assist with a land line on the 07th October 2015, they sent me an order number ***A, and advised that they will come through to my grandmothers house on the 03/11/2015, no one showed up, not even a phone call to advise that they will not be coming.<br> <br> I then called them and they advised that they would come through on the 19/11/2015, which again no one came through. I received a call from one of their agents advising that he'd come through on the 01/12/2015 and he did not show up.<br> <br> I then received a call from another agent asking if the line was installed, I said no and she told me she'd send someone on the 07/12/2015, no one has showed up.<br> <br> I'm still waiting for them to install the line till today, I want to change the service provider but would really like my grandmother to keep the same number.
