Paying customer with no service

What a disaster. Since the last week of July I've been trying to resolve a new contract with vodacom for home lte. I've received three email notifications saying that this will be actioned whilst I've had two separate dragged out conversations with the call centre to activate this. Although I have the unit there is no way to activate it there is no sim card and no one is responding. Yes they have taken my money! No I don't have the service!
