C Fiber- connection drops constantly every 90+ seconds.

Problems with Fibre connection

Good day, please can you urgently assist me. I have contacted Cell C (Fiber) client services several times over the past few months and have still had no feedback or had my problem corrected. I Have a 10mbps line The Fibre into my home drops its data inflows APROX every minute and a half. This is not a problem when on the internet, but makes streaming Impossible. I thus cannot stream anything at any time, since the signal drops totally. I have contacted metro fibre and they have said the problem is not with them and must be with C Fibre. When trying to call the Cfibre technical support number ********** 273, I am kept on hold for 15-20 minutes at a time and if I hear from a human on the other line, at any time, that person invariably puts me back on hold while they "follow up" and never returns to the phone, or just drops the call. If C Fiber does not resolve this issue, I will cancel my contract and move to a different provider.
