Fiber to the Home

HI

I have Internet outage on my fiber line for a week, reported the issue on Monday 10 September 2018 now a week later now resolution 14 September 2018. I have called both Cell C and Vuma contact center for multiple times each day and kept on hold every time and evertime I get told that theres nothing they can do - Either the back office has to attend to my query to that they cant reach the technicians. Either way I get told to contact Vuma tell by Cell C or vice versa.
