Confirmed cancellation but still debiting my acc.

To whom it may concern,<br> <br> I have been querying this issue this the first week of September and to date had no joy. I have received calls from Jonathan from Mondo on two occasions confirming that the contract has been cancelled and the refund is in process. I have contacted Vodacom and they are not aware of any cancellation. Can someone please contact me to confirm this cancellation and that vodacom has been notified of the refund and when the refund will be paid to me.
