Failure to deliver IPhone 6s 128GB Rose Gold

On the 24/11/2015 I upgraded to the MTN 200 Promo (Subs R184 &amp; Promo R358) for an IPhone 6s 128GB Rose Gold that I got debited for on 13/12/2015 and 13/01/2016. I have not received the phone. Arrangements were made that I would receive the phone during January 2016. On the 13/02 my subs was changed to R114 MTN 100. I got a call 2 weeks ago stating that the IPhone is not valid on the MTN 200 and must upgrade to MTN 350. This after I received confirmation e-mails that MTN would re-deliver the device. And after a call that Rose Gold is not available and received e-mail requesting that I order different colour - option chosen Gold.<br> 1.
