TERRIBLE FIBER PROVIDERS

I have a fiber line with vodacom. And 3 times a week (like this moment at 11:40pm) my fiber has gone down. I checked Google and according to the website the consultant's are available for 24hour however I cannot get through to anyone. This goes on everyday week for hours yet customers need to pay the full amount every month. When 3 times a week for a minimum of 3 hours it's not working. I question the quality of service provided by this what would be belived as an excellent service provider.
