UNAUTHORISED DEDUCTION!

<p>I had a top up contract with Vodacom. I requested a quote on paying this contract off (premature cancellation) because I was moving overseas. I paid the quoted amount within the 7 days that the quote is valid for. Vodacom took extremely long to confirm this payment and to cancel my contract and I had to constantly follow up (which is not my issue, but just a sidenote). I paid this full amount in JUNE and now in AUGUST, my account is deducted R395.39...?????? How is this even possible? I PAID THE COMPLETE QUOTE!! WHICH MEANS YOU ARE NO LONGER AUTHORISED TO DEBIT MY ACCOUNT!!!! I emailed the person that assisted with my contract cancellation, but ofcourse - no response!</p>
