CellC, the Worst service ever....

Towards 20 October 2015, I upgraded my 3 contracts with Cell C. 2 was upgraded in due time, the third is still pending due to various issues one of which was the availability of stock. While stock came in the order was still not fulfilled due to the order saying Gold and only sliver and gray was available. I repeatedly asked for a colour change, but that has not happened. No I cannot cancel my contract in order to port my number in order to have a phone for my son by Christmas because cell c cannot cancel my order and thus cannot cancel my contract. It also does not help if phone calls to these departments only gets answered after holding between 15 and 40 min per call.
