Webafrica vuma fibre worst ISP in south Africa

I had two fibre lines with webafrica,I cancelled one line using the app ,the feature although it shows you have cancelled the product does not,I was billed for another month and then told I have to do it via live chat and give another months notice they have basically fleeced me for another two months ,I went on live chat via the app and cancelled both my products,chatted with thabang who then put me to phaphama who refuses to give confirmation that both the services are now cancelled.you cannot call or talk to an agent only chat which is insane webafrica is by far the worst ISP provider .they don't give proof of cancellation so they can keep billing you ,when your line is down it's the same you can only chat and after waiting painfully long to get a response you have to wait a few days for them to resolve.
