Vodacom debitting incorrectly

So I am writing this review in total disgust at the type of service I have received from Vodacom regarding debits that was deducted from my account and issues were raised and not resolved. I recently upgraded with you and debit orders were confirmed. Next moment I get debited by more than double the amount. I then called in to querrie this and got a reference nr but nothing came from this and no feedback was provided back. I then went to Centurion mall to querrie it face to face and was treated as if I am the one that did wrong. Two weeks later I still have not received feedback and went back to the shop just to again be told they can not help me. I run my own business and can not waste time getting this sorted out.... Please advise and sort out your system to fix and provide feedback or I will be going to the Ombudsman if this matter is not sorted out.
