Poor Service

I requested an update on an incorrect address, they failed to fix it and debited for an incorrect router due to the issue after I had requested that they cancel the subscription on the incorrect router. Now I keep getting debited for the wrong router, no connection and their communication channel is not user friendly. Just WhatsApp no call centre, no sense of urgency, it's the worst ISP in the country. I've been waiting for this issue to be resolved since Monday. It's Friday today.
