Billing on two bank accounts for one phone!

So my wife went to Kolonade to upgrade/renew her phone contract. She also chose a new contract and changed the banking details from mine, to her new one.<br> So Vodacom decided to deduct R1215 from my account and then another R1300 from her account, for the same service and the same month. Also she went onto a higher contract, to ensure not extra costs with data.<br> RED ADVANTAGE, for which she never received the extra sim's as advertised. And the costs are not what they stated it would be...as always. So now I would like to know, how long this will be before Vodacom refunds either one of us, for DOUBLE BILLING!!! Surely this is *****?!
