Cell C Fibre

To start off if I look at the people reviews, I do not pick up that there is any response, it let a person think does it help to leave my review. Let me take a change. I have a contract by Cell C for fibre but the last 3 weeks my internet goes off then I have to lock a call. When I call the excuse they always using is it is fibre itself and not them, just after I close the call my internet is back on. They cannot admit the problem is from their side. And how do I now it as the people in my street is using the same fibre line it is just we have been taken by different server providers. It happened in the pass that we all are out at the same time then we know it is fibre itself. But to come back is the last 3 weeks was not the case. And now again my line is off from last night 8:50 and it is already 14 hours off. They sticking to it is fibre, but why is all the over people who is not by Cell C, there internet is working, and the people who is by Cell c internet is not working? We have to pay for a full service but just getting half of what we are paying. Is there not a low by clearing this is not fear, as I see it as steeling from us?
