Webafrica: Lack of service

I have reported intermittent fibre internet connection to Webafrica over an extended period of about 6 months now. It is almost impossible to talk to someone in person - the waiting times are hours and mostly you get cut off after an hour or more. The WhatsApp bot is worse. I waited at least 3 hours for a response from them with my last attempt. They keep upgrading my problem to Frogfoot. I have had NO response from Frogfoot at all. All i receive are messages from Webafrica informing me that they have resolved the isssue and they have now closed the file. The download speeds vary from 0.11 Mbps to in the 40 Mbps range with an average of 5 to 6 Mbps at night making it almost impossible to watch Netflix. I need to reboot the system multi times a day. How do i get this issue resolved! No one to talk to - no proper feedback - no rectification of the problem?
