Fibre Router Activation

Fibre was installed at my house on 12 July 2020. Till to date, 17 July, the router has no Internet access. I have spoken to six people already, only today before lunchtime. I've been calling Vodacom everyday since the installation. However, they keep escalating (following up) the issue to their team leaders, project managers, promising to call back in the next 20-30 minutes. None of them have called to explain why I still don't have Internet connectivity. My Service Request was assigned to Naomi Kekana on Tuesday, 14 July. I have not had any form of communication from this Naomi. Their service is very poor, to say the least. They have no respect for their customers at all. What does one have to do to actually get service delivery, for which they're paying for?
