Sim swop still not done after 2 weeks!

<p>I went into the N1 City Store to have a sim swop done on the 23rd June, I went back again on the 30th June and I went into the store yesterdy (4th July), the sim swop has still not been done! This is terrible service and a complete inconvenience! I was told that the issues were due to the new system, but how can this take 2 weeks for something as simple as a sim swop? I've had to pay for a sim that is not even working! I'm paying for a contract that I was unable to use for the past 2 weeks. I want this sorted out today!</p>
