Impossible contract cancellation

Dear Telkom. I have been struggling for 2 months to get an upgrade phone.Thus I decided to stop my contract and requested that my number be made pay as you go and ported to Vodacom. A cancellation form was completed, signed and email by myself to your cancellations department - [Email Removed] A week later (somewhere in the week of 8 Jan 2016) I went into your branch at Greenstone Mall, at which point the guy told me that not even a case number has been opened. He then (very grudgingly) opened the case online and provided me with case number: ***9. He also told me to give Telkom 20days, but that someone will phone me to verify the cancellation. On Saturday 6 Feb 2016 at 5:21pm Telkom phones me and escalates the case. Then yesterday, 12 Feb 2016, I have an online chat with your call centre after which the lady tells me that a manager will phone me before the day is out. No phone call. Due to the escalation it now shows that my cancellation was only submitted on 6Feb. Go into Woodlands branch, same thing - a manager will phone. No phone call. Ive complained on facebook. Still no action. ABSOLUTELY PATHETIC!!!!
