Incorrect colour cellphone delivered

Received a call from Cell C Direct to upgrade on 2 contracts on 18/11/2015. Agent advised that I can upgrade to a Samsung J5 phones. I was asked which colour phones I would like and I requested GOLD phones. Upon delivery today, 19/11/2015, the phones that were delivered where not the colour I requested. I receveid BLACK phones. I contacted the call centre and was advised that they are out of stock on the Gold phone and could not provide me with a delivery date for the new stock. This is false advertising and i would appreciate it if 2 GOLD phones could be delivered as per my telephonic request.
