Telkom...NOTHING but NOTHING happens

I phoned Telkom for a line shift on 11 November 2017....I have had 4 installation dates....that I took off from work because I HAVE to be there for installation and NO one pitches up. A Telkom manager promised to phone me which never happened. Tomorrow the 15th of January will be the 5th time I have to take off from work and if the line is not installed I will be taking Telkom to court for loss of income and breach of contract...I really hope that someone from Telkom takes action before I do. I am not threatning Telkom, I am stating that if tomorrow nothing happens, I will sue for loss off income and breach of contract. In the past I have not had any trouble with Telkom but at present Telkom is a PATHETIC service provider.
