Taking money without consent and atrocious service

I've had webafrica for the first time from December and it's the most ridiculous and atrocious customer service ever. I app**** for a PROMO they were running in December 2025.it took l 3 weeks to install Fibre. The promo was R395 for the first 3 months then R495 thereafter. I was charged R648 in December, R602 in January and R699 in February. They deduct any amount because it's difficult to get hold of them and if you reversed the debit order, they will stop the service. I've been on the chat line from 08h22 and it's now 15hoo and not resolved as yet. This is the most atrocious device provider and they are taking monies out of my account without consent. I called and was put on hold. 20 minutes later I was number 25 of 30,so to reach someone means I have to wait 2hrs on the line. That's how bad their service is. I'm fed up.
