No internet connection- Ref 16CNK171120

Good Day, I have been having an issue with my WiFi it will now be my third week without any internet connection. I have been working late and by the time I put the TV on and need to use the WiFi its already late, after the third day I tried to contact you guys however it was out of the trading hours so I logged a call request. The first fault lodged was last week Tuesday 17/11/2020. I was scheduled an appointment for the 20th between 8am to 4pm, nobody pitches up! I go back on the app and now I'm scheduled for the 24th ! I practically have not had WiFi for the whole month! I have been purchasing so much data to keep my daughter occupied. You guys cannot expect me to pay my full monthly subscription. I would like a response as to the way forward and how soon this can be resolved as this is totally unacceptable. Thank you .
