TELKOM REFUSES TO CANCEL MY FULLY EXPIRED CONTRACT

As per my previous complaint Telkom STILL HAS NOT CONTACTED ME. All I want is for this contract to be cancelled. I have signed a form in store but it carried on billing. Visited twice to a branch only to be told they tried to \confirm"my cancellation by calling me but no one called. I called a call centre but they cannot help me. I am confirming for the 10th time to cancel this contract. What more needs to be done. If you have tried to call me then you must have the wrong number. My number is ***. Please can some one please please please just cancel it. I don't want another email from Joshua @ the social media team telling me someone will be in touch because it is a lie. Please sort this out as soon as possible!!!!"""
