DSTV INTERNET with no internet 😒

I have had the DSTV INTERNET router delivered to me from 3 weeks now, I have been calling them non stop but every time I speak to someone we start from the beginning and they all give different answers. I even went to their store where i was told on this Tuesday that the person who was assisting us, got the address wrong and that they fixed it but when we got home still no difference. Called again but still no lack even bought R100 extra airtime to be told that they can't call back and that we should hold for long minutes with them not coming back to us, we can't even cancel it because we keep being sent from pillar to post. We are now tired and feel that we want to cancel this as we can't pay for something that we can't use. Either we get help connecting or we cancel all together
