Regular telephone line outages

Telkom has to fix my line on regular intervals, last ticket I logged 476CTK120917 was logged on Tuesday 12 September @ 18:09 as line was dead and my line was only fixed the Monday 18th September. Line dead again on Saturday 23rd September and logged ticket 141CTK230617, after which I called the callcentre to sort out as I did not even have a working line for a week, I was told that a technician needs to be authorized to work on my line. Why can they not fix the line on the 1st go???
