Vodacom *****s clients' money it is not only the government

I have posted so many poor reviews about Vodacom's poor service and accountability with cancelling a contract for my brother who lives overseas now. I have been told i have been told 3 times after the last poor review that an agent will call me. As yet no one has and the money promised to be refunded has not been fulfillled. Can anyone advise me what is the next step? Carte Blanche. Has anyone tried that? This is downright *******. I just got an SMS on my phone giving a reference number that has never been used by me or my brother and saying the case is closed. It certainly hasn't been solved yet. They have filched at least 1200R of what they promised. I am not leaving this until it is properly settled.
