Vodacom's empty promises and really bad service

I have been requesting a voice recording of the retention call from Vodacom for over 4 months, called numerous times and been promised it is escalated each time. The customer consultants, retention and management at Vodacom due not keep their word. They keep deducting different amounts frommy account though nothing changed and it is fixed. They make sales and tell you how much you will pay but it is not what they stated. I want to go to the ombudsman but can't do anything without the recording and even though I have a right to it, they not supplying it. You struggle to speak to them and no one calls back. Therefore now this review.
