Debit orders wont stop

September 2014 I went to Telkom to cancel my 8ta Telkom contract that I had for 3 years. They said I need a Copy of my ID and to fill in a form and they will email it. After all that the lady said it will be canceled and sorry to see me leave. After that I got no notifications and no debit order. January I got a debit order but for 2 months outstanding Bills. I went back and they said that they will resolve this problem so I went to the bank and canceled the debit order and reverted the money back. Next month 3 Months outstanding bills....So afraid of being blacklisted I paid them and went to Telkom being Furious! The lady told me they never have any cancelation of me and only the NUMBER was canceled NOT the contract!?!? I was so mad I just gave up hope. Last month be4 the 18th I've went back and canceled everything explicitly telling them EVERYTHING every number contract everything on my name. 3days ago got a debit order for 2 months outstanding again. Someone please help me how can get Telkom off my back? Every time I call them they say I must go in to the shop to cancel it?
