Deducting money after cancelation

I cancelled my Telkom mobile account in-store on the 24th of September and just saw that they are still deducting money from my account. I phoned customer service (which is also very pathetic, was in the queue for 20 min) and they said they tried to confirm the cancellation. Firstly that was not conveyd in the store, according to me the issue has been dealt with because I filled in the paperwork to cancel it. Secondly I never received a call or a voice mail to inform me that they called. <br> <br> Telkom mobile is honestly the worst service overall, poor mobile coverage, appalling customer service in store and even worse at their call centres.
