Landline unrepairable

Telkom simply cannot seem to repair our landline satisfactorily. Over the course of the past 12 months we've had to report it out of order at least 5 times and as we enter 2016 it is once again out of order (since 29 Jan).<br> <br> All we ask is that someone from Telkom gets to the root cause of the fault and fixes it once and for all<br> <br> We cannot understand why that is so difficult.<br> <br> The current fault reference no is 418NK290116.<br> <br> Telkom, PLEASE HELP!
