Once again, no internet

Again we have no internet. This is becoming ridiculous. They sent out a notification last month to say fees are going up by R100. A day after that our internet went off for 4 days. Again today the internet is off. I want to know why they are not crediting the days we don't have internet, but so fast to take our money and increase the monthly fee. When you phone, they say phone lines are busy. No one phones back when you choose the option. Their WhatsApp group is useless. Still waiting for someone to phone back from last month's issue. Everything is always automated and I bet you the reply to this review will probably also be. When you do eventually use all your airtime and get through to them, they just say there is a problem with the network and it's being dealt with, but can't give a timeframe. People are losing money working from home and can't use the internet. I find this highly unprofessional and someone has to deal with this problem. It's becoming more regular now and nothing is ever being done. How can someone pay for a service if they don't receive one?
