3 DAYS!! NO SIM SWOP!!! URGENT

I contacted cell c on 05/10/2015 to report my phone as ******. On 06/10/2015 I phoned again to request a sim swop. I gave the consultant my new sim card's Rica Serial Number and was told that someone will contact me within 24 hours. The following day on 07/10/2015 I phoned again, where I was told it can take up to 48 hours and that no one has responded to my request as yet but they will within that day. Yesterday 08/10/2015 the consultant told me that the manager would handle my query personally and he would contact within 4 hours, this was at 9am. I phoned back today again 09/10/2015 and the consultant told me they should have contacted me already. This is pathetic as I have been with cell c since they started. I have two contracts where the above mentioned is also a contract! How can you treat your loyal, long term clients this way??!! I need this done ASAP TODAY!! I have been forced to use a vodacom sim card which has been costing me unnecessary money!!! *** 6000 68.
