Online Upgrade System for Vodacom Does Not Work

I have used Vodacom's online upgrade system before and it worked perfectly, so I thought I would try it again. It seemed to be working and I filled out all the forms and was told that the company would be in touch and my assumption is it would be delivered either the next day or the day after (I did this on the 15th of February). Now the phone is completely out of stock and by the looks of it I won't be able to get it at the February price as the month is drawing to a close. The only reason I used the online system was because I am busy and don't have time to go to a Vodacom store and thought it would make my life easier.
