Over debited my account

<p>I upgraded my cell phone in December and moved the debit order to my own account. Lerato in the Vodacom shop in Lakeside mall said that the December debit order would still go off my dad's account which it did but at the end of January it would go off of my account. Lerato assured me that only one month will go off of my account in January. At the end of January Vodacom debited December and January from my account. I have tried calling Vodacom I have called Vodacom Lakeside mall and left messages because Lerato did not answer and I emailed Lerato a few times and have had no response. I received a call from Vodacom to say my phone is due for an upgrade and I explained to her that I upgraded and what has happened and she said I should phone Vodacom? </p>
