Paying for expired contract

My contact expired in August 2015. I went to the shop, filled in a cancellation form. I then received an sms stating that they received the request to cancel and it was successful. Desember and now in January 2016 telkom took R199 from my acc (which is half my original contract fee). When I phoned customer care, they said they need the original simcard to access my info. After *****ing about the situation they eventually helped using my ID no and said my contract still shows active on their system and that it wasn't cancelled. I have to go back to a telkom shop fill in a new form so that it can be cancelled!!! This is *****. Nothing other than a deliberate deception to secure unfair gain.
