Bad service, they can't manage this online system of their. Credit always go missing

They should honestly end these online metering systems, because honestly they can't maintain it. I went to bed with almost 200 credits and woke up in the morning to -134 credit. Two weeks later, which is today, I went to bed with 166 credits and woke to -41 and there was no power. I bought more credit again, guess what the power did not come back. I called several times, all consultants keep saying they will reboot the power will be back in 15 minutes. There is this particular one called Dineo, she was so rude. I also spoke to another one called Rudzani, she wasn't rude but definitely needs training on how to speak to customers.
