Its been 2months - how much longer????

I have been trying to get Telkom to cancel my adsl line since the end of February. I'm migrating and need the line to be placed in a holding pool for the new subscriber to pick up. Everytime I called the 10210 number, I have received numerous answers to my query, request for reference numbers to be sent to me - none came through, promises of managers that will call back - I'm still waiting, different email addresses to mail with regards to query - still no responses.. I sent my cancellation form in twice - and there's been no response. I have add agents hang-up on me and blatantly ask me \now what must I do about that\". The service has been beyond excruciating and my line has still not been migrated. I fully understand that there would be a process for everything and that a certain amount of wait time would go into a request. Its only been 2 months later..."
