Horrible fiber Service

If I could give 0 star I would, This is not new, with Vodacom, if not messing up with the contracts they have a very terrible service, lately their fiber department. My home fiber has been out since the 19th of March at least then it's been on and off, but last week on the 3rd of April it completely went offline with the ref light on the ONT showing a solid red alarm light. I logged an SR and I have been on call with them for the past week last week with different agents telling different stories. Somehow they mentioned escalating the issue to Vuma who are not responding nor attending to the issue; this was not part of the the initial contract with thm. When I cancel they refuse and are not sending the SR number for the cancelation. My entire home system is offline for the past week and I am also working from home which is not helping the situation. I need a cancelation and a refund so I can get am LTE router from another ISP and now they are not taking my calls.
