Telkom deleted my number without my permission

My contract with Telkom expired and then went into autorenewal. I was not informed of the autorenewal until I queried why I was still being charged. I then asked for a cancellation and asked that my number be moved back to a prepaid line. The person assisting me assured methat this would be done and that it would take 24 hours to take effect. That was 11 days ago. My number is still not working. When I made a follow up I was told that my number had actually been deleted off the system and no longer existed. Again I asked that it be reinstated and I was told they would escalate it. They gave me a case number (***2) and said it would take between 2 hours and 72 hours. That was over a week ago. My number is still not working. This number was never a contract line to begin with. I had ported my number and migrated it to contract to avoid having to change my number and now I cannot get it back. It is linked to all my accounts. I have made numerous calls to Telkom but I am always told that "it has been escalated". However the higher powers are, I need them to get in contact with me and sort it out once and for all.
