No one knows anything

I've placed an order on 12 Feb 2015. The following week I was contacted and told the device had been discontinued, and then requested that my application be cancelled and logged a complaint on Hello Peter for the poor advertising. A month later I tried to apply for a Vodacom contract at a store and it cannot be processed because the old application is still pending and NO ONE knows how to cancel. Not even one person. I've spoken to Online, After Sales, Cancellations. The consultants have spoken to Acquisitions, and even IT. No one at Vodacom knows how to cancel an order.
