ADSL fault logged 23 Oct 2017 and line is still not working

Logged a call for the line that is extremely slow and disconnects from time to time. First it was the modem, but we replaced that and the fault remains. Then it was us not correctly plugging the line in, Tech came and plugged in the line and the fault remains. Now it seems Telkom agree the problem is with the line and it needs to be replaced. The line is not on my property and Telkom cannot get access. I waited in front of the property till the owners came home and arranged two days for Telkom to be able to gain access and replace the line. The two days came and went. Telkom did nothing.

Where do I go from here? 5 weeks later...
