absolute worst customer service

We have been struggling with extremely low download speed for more than 2 weeks now. We are paying for a 50meg line, which we are not getting at this stage. Trying to get help from WhatsApp or the website proves to be futile. Every time we get told the technicians are looking into it or the problem is with vumatel and they will come out to see what the problem is. For some reason Vumatel never has the right address and blames web Africa. Our line fault has now been escalated to priority level 4, which up to now still means absolutely nothing, because still no one is in contact and we are still unable to use the internet for which we are paying. There are people working from home. This problem is causing them not being able to fulfill their job obligations, which results in loss of income!!! The way I see it, Webafrica is in breach of contract, for not supplying an agreed upon service for which I am paying!!! Why should I continue paying when there is no service from your end.
