Cancelled Sim Before Contract Expired

<p>In a nutshell. I received an sms that my SIM will be cancelled on 8 Dec. I had previously tried to cancel my contracts effective 8 Dec but was told this was impossible and could only be cancelled effective end of month. However I did call the cancellations number and was informed that the sms was in error because the system was loaded to terminate both contracts on 30 December and migrate both numbers to prepaid. I was already billed for December (separate review logged for a separate issue). The one sim card is effectively non functional with the error SIM not provisioned and I cannot call vodacom because I the sim is unusable. </p>
