Debit order still not cancelled

<br> After numerous attempt of trying to get telkom mobile to stop debiting from my account as my cell phone contract had expired at the end of August 2015 and i informed them to cancel it. <br> However i am still getting debited even i had cancelled, i went into the telkom store to cancel and filled in all the document required, called the call centre and i was notified that my account is now on prepaid.<br> <br> I would like to be refunded from September 2015 to current, what bothers me the most is that nobody even bothers to inform me or update me about what is going on. kindly call me on my cell and inform me what is going on. This is really frustrating.
