Vodacom the fibre less internet service provider!

I don't know how long it's going to take for Vodacom to get their act together when it comes to providing fibre internet services. Every month I pay for a 100 meg line when I'm only getting less that half that speed. Averaging between 30 and 40 megs. I resorted to taking screen shots of this ********** slow speed. I'm also having to reboot the router all the time and when I call in to their fibre department they run diagnostics, reset the router. However, this is only a temporary solution. As this seems to work for less than a week then it's back to normal. Perhaps they should stick to mobile phones and leave the internet to the companies that actually knows what they are doing when it come to providing an internet service.
