Still not Canceled

I have cancelled my Telkom Mobile Account in December 2015; to my surprise Telkom have deducted again now in March from my bank account - when will this end and when will I get a refund as I am not using the account as per Telkom's advice - after they confirmed my cancelation was delayed due to non compliance on their side - waiting in queue for processing! And still not processed!<br> I thought you only need to give a months notice for cancelations - now it is running for the third month - it is totally un acceptable<br>
