Upgraded, no stock, still no phone...now billed!

I upgraded my Autopage contract at the beginning of Feb 2015 - and was then informed that the phone I upgraded to was out-of-stock - an iPhone 6 16gb - but that I could wait for it. The upgrade consultant gave me her details to keep contacting her to check on the order of the status.<br> <br> So basically I have just been continuously now told that stock should be available 'next week' and to phone back then. So I have kept following up only to hear the same story. At one point a consultant actually went as far as to say that I would have a phone by the end of the month (Feb).<br> <br> Now I have just found out that I have been billed for the phone this month - when I still don't even have it!<br> <br> Another call today (4 March 2015) and I was told that that is how it 'works' you get billed for it even if you don't have the phone yet and that if you don't like that then you can just cancel the upgrade!<br> <br> After being a customer for what must be close to 15 years I am now at a loss as to what to do - two phone calls to Vodacom and MTN stores in my town today confirms that they both have stock waiting....?<br> <br> Please advise?<br> <br>
