Poor customer support and wrong billing

This is day one of me using Webafrica and probably my last day. They claim to have 3 ways of connecting to their customer service: e-mail, call, What's App. None of them are answered. I have spend more than 2 hours on the phone since I signed up in in Feb (for activation 1 April) and if you eventually get through the person on the line cannot assist. Same with What's App. Emails are simply not answered at all.

I signed up for unlimited uncapped fibre line speed of 20Mbps for R699.00 per month. I just received my 1st invoice and now they added 15% VAT to that! You cannot quote and advertise a price without VAT!
