service messed up my sim card

To whom it may concern<br> <br> I want to comment on the lack of service from Vodacom, I clearly requested that my top up contract be cancelled and converted into a prepaid sim, which I was assured that it will happen. So on Thursday I took half day from work, I went into Vodaworld, I requested a quote for the cancellation and completed the payment. Everything was complete from my side, only to wake up this morning and my sim doesn't work anymore. The error that I received is \SIM not Provisioned:2". So I called the call center and was on hold for about 40 mins"
