Cancelled Contract - SIM not provisioned

Tired of complaining about your service<br> <br> 1.<br> My contract was scheduled to be cancelled on 31 Apr 2015. Technically I should have had the 31st to finish my airtime and data. However my phone since 7 this morning has been giving me an SIM NOT PROVISIONED:2. error<br> I shouldn't have to forfeit my remaining airtime. <br> <br> 2. <br> How can I get my number moved to prepaid if you do not answer your phones ??? You have a backlog of unanswered complaints on this site 10 days deep ! Am I going to be without coverage for 10+ days ? <br> <br>
