No response to serious mistake

<p>On the 29th of July I called 111 call centre to add an addistional 60 min talk time om my cellphone. After not receiving a sms to confirm this I called them again and was informed that the previous lady I have spoken to has added an unlimited talk time for 30days at R999 to my accout. Since then I have made several calls to vodacom to explain that I did not ask for this and that the R999 should be reversed on my account. I asked them to listen to the call recording and they would hear that this is not what I requested. Since then I have been calling 111 on a regular base to find out the progress and everytime I'm informed that the dispute is still open, it'snot been assigned, it hasn't been attentended to. This is absolutey outrages as I will not have enough money in my account at the end of the month for that additional R1000. This will mean the bank will return the debit order and I will incur further bank costs ontop of this. It is abosuletly unacceptable. And no one wants to put me through to a manager or supervisor. I'm completely at my wits end.</p>
