UNSTABLE FIBRE CONNECTION VODACOM

I am so upset at the terrible service I am currently receiving from Vodacom

2-3 weeks back our fiber connection was down close to 2weeks a technician came on site and told us that the problem was with the complex fiber the guys from there said the issue is in actual fact Vodacom's fiber another technician came "fixed the problem" and it as okay for a few days on Friday it got disconnected for an hour and came back on Saturday again it got disconnected and still I am without internet connection I called the call center asking that they send a technician ASAP was put on hold for 30mins line disconnected and the lady never bother calling me back the service I am receiving is sacking to say the least might as well cancel the contact because I am paying for nothing cos that's what I am getting ref sr***
