Struggling with line installation

I have been trying to get my line installation done since November 2017. After struggling to get technicians to come out and install my line, a temporary line was installed. The gentleman said that he will log the call so that a permanent line will be installed. I lady phoned me on Monday (26/02/2018) to tell me that my call was logged and the rectification will take place.

Since I work 12-hour shifts 6 days a week, I was unfortunately not available on the specified date (05/03/2018) and I tried to reschedule the date. On the website I was notified that I have no pending request, this was concerning to me since I was assured that it was logged. On the due date, I received a message stating that a technician is deployed. I immediately phone customer care to inform them that no one will be at home. The gentleman then phone me shortly after, I told him what the situation was and he said that he will come back on Thursday (08/03/2018). I received no phone calls on Thursday nor any message.

I am really trying to stay patient during this process, but it has been more than 3 months and I am growing tired. Please, can someone assist me with this matter?
