Poor Service

I upgraded my contract with Cell C on the 28th of July 2015, to my surprise 3 weeks later I still have not received my device. I was told I should receive the device within 48 hours. A week later I still didn't. When I called I was told that the color I was looking for was out of stock. Then I changed I requested to change the color. A week later after that I still didn't have the device. When I called I was told it because they didn't not have white phones in stock. I was surprised since I had changed the color the previous week. After 2 days I decided to call again only to be told the same thing about the color which I requested it to be changed...again!!! Then only on Tuesday last week I called again and still to be told the same thing about the color...then I requested to cancel the upgrade. I was given a reference number and was promised that someone will call me back...to date no one has!!! But on Friday I received my device from the courier company<br> Now I called in yesterday to do the sim swap...I was told someone will call me back to activate it but it will take 8 hours since there was a backlog and was given a reference no: ( ***). Till now, it hasn't been sorted.
