Cancelled my line for no reason

I have had a contract with Telkom mobile for more than 24 months and I requested for cancellation after I had realised that it was on a month to month bases. I spoke to a lady by the name of Sinenhlanhla who was trying to sell me an upgrade. I requested Sinenhlanhla to assist me in cancelling the contract, she then forwarded me the cancellation form, which I filled in. In the cancellation form I requested for my line to be migrated to prepaid but now my line has been completely cancelled. I went into the Maponya mall store where they sent an email lodging a case and I have made calls to the contact centre, everybody keeps telling me that they have escalated the matter but nothing has been happening. The most depressing thing is that there are cv's I have sent to different companies containing that number only and now I haven't had that line for more than a week now because of someone's incompetency.
