Telkom deay tactics on cancellation requests

I have been trying to cancel my Telkom line for almost 3 months now. last week I was told that the line was still linked and I had to call openserve etc to obtain the Telkom reference to confirm the line had been moved to Telkom's holding pool even though Telkom has this reference. I was then told that it would be cancelled and someone would contact me to confirm but of course this was not done and I was once again debited.
