Webafrica fails to sort out billing issues.

This has to be the the worst internet service provider business that I've ever had the displeasure of dealing with. I have been trying for almost 8 weeks to get them to fix a invoice problem that they created, but to no avail. In fact, today they just doubled my bill. To put this into perspective, I migrated to a R400 per month package on 1st March 2020, and they have now set my bill today on the 22 April to over R2800. I can only say that after 6 or 7 tries via various means, they have failed to rectify the problem that they originally created. I have no alternative but to supoena the CEO to court to explain why and how they have caused so much trouble at their useless call centers. The first time I complained a representative said, they had fixed the problem(on this platform) well no, they did not.
