appalling Service

I ordered for a voice line to be installed in my flat over a month ago. I specifically requested it to be done on the 1st of December 2017 and I got an sms confirming it will be done on the day and got another sms stating that the technician is en route to do the installation. It is now the 06th of December and I have not heard a thing. I specifically missed a day of work on Friday to wait for the technician and nobody arrived nor did I get a message to say he is not coming, so not only did I already miss a day's wages but accomplished nothing. I have gone into the Musgrave store a few times already to follow up and complain but nothing seems to be done nor have I been updated, this is why I did not want to deal with Telkom/openserve. I sincerely hope I will get a pro-rata for this and would like some sort of feedback on when my line is going to be installed.
