called to cancel and they havent cancelled

I called through to arrange payment after missing a debit order and to cancel the debit order on my account. <br> <br> My account was deducted for the amount owing and the full amount for this month was deducted. I was advised that I would only pay R247.50 that was outstanding and R120 for the cancellation debit order and not R247.50. So I take it that my cancellation request has seemed to disappear into thin air. This is 2 months after my 1 year contract has expired and as per contract after the initial 12months a client can cancel at anytime. Cancel the debit order and refund my R127!!!
