Contract phone upgrade - waiting for 3 months

I first contacted the MTN store in Kolonnade Mall on 1 August to arrange to upgrade my contract. Belinda informed me that the phone I was looking for was not available but that she would order it and contact me when it was received. After three weeks of no news I visited the store to check on the progress but was told that the phone had still not arrived. I phoned a few times during the course of the next weeks but was always told that the phone would be arriving in the next week.

Finally I'd had enough of that specific MTN store and contacted MTN in Menlyn Mall. Thomas gave me the same story about the phone being out of stock, saying he would order it and let me know when it arrived. I waited for another two weeks and when I contacted the store again, Willem told me the phone would be arriving in the next week.

It is another two weeks later and more than three months since I first contacted MTN. The phone that I want is one that is advertised as available in all of MTN's printed adverti*****ts as well as on their website. MTN did not contact me once to inform me of the status of my upgrade request.
