Contract not cancelled

From my last complaint a month ago nothing constructive has been done from Telkom. I had a call from a lady that explained to me that the complaint was sent to the wrong department and that she will get the right department to contact me that was 2 weeks ago. Contacted the call centre numerous occasions still no help could not even get the legal department contact details. Telkom is not a trustworthy company as they keep billing me for a contract I cancelled in November 2015 (REF ***1). Please check your Telkom bill u could be paying for something you don't use.
