Complaint - they stole my sim and credit

My prepaid sim and cellphone account *** has been deregistered by Vodacom, apparently because I had not used it in 7 months. Nearly half an hour on the phone to 082 111 elicited a response that they would try to see if the number can be restored. No undertaking about restoring the prepaid credit. So far as I can tell this is covered by S63 and/or S64 of the Consumer Protection Act and they have no right to do this until three years has expired. I would like my service restored pronto and my available call credit restored as well. Would also like to know why they think this does not fall under the CPA as mentioned
