Advertising deals but no phones in stock

<p>Went to MTN to upgrade my daughter's contract to the Apple 6 16GB for R339 on MTN choice 100. I was told that there is no stock, so they can try and order but some people have been weaiting 2 weeks and they don't know how long we will wait. How can you have offers in your brochures and then not have stock of the phones?? I also nowhere see anything about while stocks last as the sales person said to me.</p>
