Don't upgrade on the internet.

I did an upgrade on Monday 4 November on the internet. Got a confirmation email a few minutes later. Call them yesterday 5 November to find out when delivery will take place only to be told that the Confirmation department must call me before the upgrade can be done. First they said they will call me within 24 hours and when I said it is already 24 hours they changed it to 48 hours. I called them again today to say nobody has contacted me yet. After being put through to 4 person they lady inform me that they did try to contact me but I didn't answer and even gave me the number they called me on. The number they tried calling me on is my Data contract, not even the contract I'm upgrading. So now I have to wait again for somebody to call me, hopefully on my number (which I'm upgrading). I find this very frustrating. Surely they can see on the system the number is a data contract. If I went to a Vodacom shop the upgrade would have been done already.
