Afrihost are useless

I signed up with Afrihost for internet service on the 30/10/2022. Metrofibre came to do the installation and set up of devices on the 31/10/2022. Firstly, Metrofibre didn't activate the line for about a week. I spent hours on the phone/whatsapp/emails trying to figure that out. Since then the internet does not work on any of my devices. Every time I chat to support they make me start the process of checking fault from the beginning of the process. They keep telling me to log onto Afrihost while connected at home but I cannot log on because there is no internet. My devices connect but there is no internet since installation. I have spent hours and hours trying to get assistance with positive results. My partner works from home and needs internet to work. He has had to use mobile data Afrihost are USELESS. I will cancel the service if I do not have internet by the end of this week.
