After hours of fixing the issue a day later they "call bar limit" and I have the same issue again

<p>16/08/04 at 11:46am I call 111 because I saw they billed me for my previous 1gb Data contract and not the S7 I upgraded that Data contract too. They said everything was fine. That I would be billed the following month and that the S7 services would change this month. 16/08/05 at 13:00 I get a message saying "Your Credit Limit Bar has been activated" along with this message they cut all my services. I can call emergency numbers and their call center. I called from about 13:10 until 15:00 and eventually after much frustration I went through to their cradle stone branch and had the issue sorted out. This morning 16/08/06 I puck up my phone and I have the same Credit bar message and no services. I am Canceling my Contract. I have been on hold for over 30mins. Vodacom. You guys are useless and I hope this prevents someone experiencing the same frustration and rage that I have</p>
