Don't take Fibre with Vodacom

I have been calling Vodacom and lodging Complaints with them almost every week since they have activated my Fibre line. On Friday again the frustrated me, called them explaining I have just done a speed test and it shows 2up/2down. I explained to the guy that the lights on the ONT are just flickering it is never stable, H mentioned that the link was down and that he would escalate it. Last night I tried streaming a movie and it could not play, it just buffers. Its either they are throttling the line or the signal in the area is just extremely poor. I explained to the guy that I could not use this line since the day it was activated, he assured me that they would sort it out. Now a good few days later and I have not heard back from Vodacom. They do not know how to manage the Fibre side of things. Rather go with a more established Fibre provider than Vodacom.
