Number Cancelled without consent

I requested for my telkom mobile number to be migrated to Prepaid after my contract ended in November 2017. Instead my number was cancelled, this means I have no means of being in touch with the world. no one at the call center can help me. been given a run around and numerous references. always have to be the one calling and holding, I have spoken to one of the TL who promised that my query would be resolved. to this date i am still without a working mobile number and have spoken to an agent by the name is Siqobile who made me feel like the reason the number was cancelled was my doing. this is unacceptable from Telkom and very disappointing!!!!!!
