Telkom Business Cancellations

As per instructions from the Telkom Business cancellations department, I sent an email on 31st Jan 2015 to cancel my Telkom line. I was told I had to give 30 days notice. I called 2 weeks later to find out if the process was moving along and was informed that they knew nothing about it. I forwarded the cancellation again. When I called back a few days later, nobody knew anything about it. I was told that it had been escalated and that somebody would call me back. I waited 4 days and nothing had happened. I managed to get hold of Floyd, the cancellations manager, and he assured me that it would be sorted out that day. Once again, it was an empty promise. Nothing has been done. I have spoken to the accounts, cancellation and sales departments and nobody can help me. I have reached the end of my thread. I would like this complaint to end up with the CEO. The number I am trying to cancel is ***, account number ***.
