Billed after moving to prepaid

My 2 year contract agreement with MTN had expired at the beginning of September. I was told that the number would now have to be moved to Prepaid to ensure billing no longer takes place. I was also guaranteed that no additional cancellation fees would have to be paid as the contract 24 month period had finished. Today i received notice that R225 had been deducted from my bank account, even after moving to prepaid.<br> <br> What was this R225 deducted for?<br> <br> Im clearly not receiving airtime nor should i still be paying for a cellphone after the initial 24month contract agreement.<br> <br>
