Webafrica is deliberately ********* and ***** when cancelling your service

I have spent over 90 minutes trying to cancel my fiber, and still nothing from them. They do not allow you to cancel your service online/self serve and force you to use their horrible chat app.

First when you open the chat app, it is a bot with no options on cancellation. Eventually you get through to some customer agent, that staggers their replies 2 minutes apart. One of the replies was 5 minutes apart before they let you know that they can't help you and transfer you to another person, who does exactly the same except the next transfer took over 10 minutes. Eventually I'm chatting to a person that offers to phone me to talk about the cancellation (probably trying to get me to not). Eventually we start talking about actually getting to cancel - yay. This is now over 80 minutes in.

After asking for all my details for a 3rd time, I have to wait 20 minutes for a response asking about an attachment.

I have screenshots of the entire conversations, and as of typing this. Nothing has been resolved.

How is this kind of business practice even legal?
