Vodacom No Internet Signal - Nobody Coming Back in Cape Town Area

We have had no signal in the area in Cape Town (Northern Suburbs) for over 4 weeks. we have logged several service requests. We are currently paying for a product aka data sim (premium rate). Which we cannot use. They keep saying that they need to adjust the service request and the area. We have spoken to Managers and still empty promises each time. When you go to other areas Cape Town there are 5G and more.
