Vodacom - Very poor response to billing issues

<p>Trying a month now to sort out my vodacom bill. Contacted them a few times with no resolvement... They adding data bundels without my signature to a contract or my "ok" on voice recording. Taking extra money from my bank account and just cant get this issue sorted via customer care. I am a vodacom customer for over 10years but considering to cancel all my contract and move over to someone else who is cheaper and who will provide better customer service...</p>
