Unacceptable service

We have paid our Telkom bill in full but our service is still suspended. I have tried phoning within the working hours stipulated and each time it tells me that I have phoned outside of operating hours. I just tried again. It is not 17:30 yet! I have also tried messaging them via the app last night. They said that someone would phone me back shortly and we are still waiting.....once again within their mentioned operating hours. Our kids were unable to access school work and are now 2 days behind because of it.
