Sim swop

I lost my Sim card and went to a cell store for a Sim swop for a contract data Sim. I had to pay R116 which is absurd, but anyway I did. Was told to only insert Sim after 2 hours, I only put the Sim in the phone about 4 hours later when I was done at the mall and got home. Fast forward, 2 days later Sim card is still not picking up on any of my phones. I called the call center, they don't know what's the problem and said I must go back to the cell c store. This is ridiculous. I am a paying customer, the fact that you charge so much for a swim swop is **************** and still for the service to not be provided to me! I cannot be expected to use more petrol and create time that I do not have to fix your problems.
