Horrible Service

I reported that I was relocating last year December and they must book a technician to come and install a line where I was moving to. I was told a technician will come on the 8th January 2018. None came I called today and I'm being told my case is at the back office. I asked call centre to escalate the matter she kept me on good for about 30min and our line got cut and she didn't even bother to give me a call after I gave her all my details. Telkom should really do something regarding holding time. I still don't know what the problem is because when I called back I was holding for almost 15min. Telkom is the worst service.
