Refund Due after cancelling contract

I cancelled my MTN contract in September at the MTN at the Mall@Reds Centurion. The consultant that helped me was Ashley.<br> It was cancelled in the middle of the month. I was assured that because I cancelled in time there would be no further amounts be deducted from my account by MTN. <br> <br> Then in the beginning of October my premium was deducted again! <br> <br> I went to Ashley again at the shop and complained. She assured that she would keep me updated and would raise it with MTN and I would get my refund asap.<br> <br> It is January and I have not been properly updated nor have I received my refund. <br> <br> I have contacted her last week and today but have still not received my refund.<br> <br> This is not acceptable to me
