Noone in the whole of Vodacom can view my order number

I placed an order for a prepaid device through the Vodacom Online shop. That was on Sunday the 17th. I'm going away on the 22nd and so need the phone before then. I've been sent back and forth through the customer care team, the online support team, the sales team, numerous email accounts, yet NO ONE can even view my order number to confirm when I will receive it. This despite the fact that I have a confirmation email from Vodacom. How is it that not one department can view an order. and instead of trying to find a solution internally, it is me that they keep sending between all the departments to find a solution. Quite fed up really.
