Order telephone line/DSL. Installation not done

So I placed my order well in advance because I knew that I would be moving into my new place end of this month.<br> <br> I got a confirmation that my line will be installed on the 16th of September between 08:00 and 16:00, order number: ***. Technician never pitched to install the line, claiming that no one answered their phones, except for the fact that I never got a call, nor did my fiance, who's number is listed as the secondary number.<br> <br> Phone telkom on Friday, agent tells me that he will reschedule the installation for today and confirmation will be sent. Never got any confirmation and according to the agent I spoke to just now, that never happened because \there are no more installation slots for this month".<br> <br> The agent now apparently \""escalated\"" the order (***)"
