Activation process

I moved recently and had to change my address. The old contract was canceled and a new one requested for the new address. The activation date was supposed to be 1 December. I was informed that it would take 48 to 72 hours. It's been 4 days now and I have not been contacted regarding the activation. I am not sure if there is a miscommunication between forefoot and supersonic? I did get through to the call centre after continuously calling for an hour where I was assured that the person responsible for the activation will contact me today. No contact has been made. I tried calling the call centre again this afternoon, for about an hour, they simply do jot answer. I am currently paying for a service that I'm not getting.
