Still being billed for cancelled contract

Earlier the year I went in to Autopage to cancel my 3G data contract. (acc no: 1.***1). I was told that I had to wait since the contract has to run the full 24 months. I went back in to the Woodlands branch and cancelled the contract. End of August the debit order went off again, for R 282.99 - my dr order used to be R 132.99 - I was told was because I upgraded. This was incorrect since I cancelled the contract. Abbie, the person at the branch, phoned and sorted this out, promising that the contract was now cancelled and that I would get the R 282.99 refunded. I never received the refund. On 28 October, I went back in to find out what the issue was - they confirmed that the contract was cancelled and that the now TWO debit orders would be refunded within two weeks. It has now been almost a month and the money has not been refunded, and I am sceptical that the debit order won't go off again end of the month. Apparently someone from the Faerie Glen Branch had phoned me and I upgraded over the phone - this is not the case and when I asked to hear the recording of the phone call, they could not find it.
