Rain

I have phoned them complaining about the network and asking them what can be done about it. Somehow they always have an excuse about load shedding. I did say that if if doesn't get better I will need to cancel with them and go onto a new wifi and they didn't care. The following day I see the wifi isn't working and I need it to do my job as I work from home. I waited abit and realized that they disconnected me completely. When I initially phoned them they said I was behind in payment one month so they need to cancel it for the whole month and I need to pay for it which I have never been behind with payment as they would of switched me off long ago. I'm not the first person with this exact story. Now my account is in minus and I'm jobless and they try take money every day or every second day so it bounces. What can I do? They canceled it before I called to cancel it.
