Running deals with no stock and no communication

I came in last week Monday to upgrade to an iPhone 6 on the contract deal for R379.<br> <br> I was told that there was no stock but that there would be by Thursday and I would receive a call. Thursday came, no call, but as I was in the centre I checked and there was no stock. I was told it would arrive Friday.<br> <br> Friday I called and there was still no stock but the lady I spoke to told me she would confirm when stock has arrived and call me back - I have still not received a return call.<br> <br> PLEASE can you tell me if you have stock, and if not, when you will. Alternatively, which of your stores do have stock?<br> <br> This level of service has been incredibly disappointing - I cannot fathom why Vodacom would run a deal on a phone that they have no stock on.<br> <br> Added to which the email address listed on the vodacom website bounces back.<br>
