CLIP activation failure, no resolution or feedback

I have been calling Vodacom call centre for over a week now and everytime I speak to a different agent who promises to escalate the matter and call back but never do! I upgraded my phone and moved from TopUp to Smart L, since the migration all calls I get come through as a private number ... the call centre agents all tell me my CLIP has been activated but there are issues doing the synch to my simcard. Will making daily calls to vodacom actually help in resolving the issue or do I have to cancel my contract in order to get the matter resolved?
