Offer made by call centre but not completed!!!

At the beginning of March, I canceled my line in a Telkom direct store due to me relocating. I received a call asking me if I would lke to keep my line and transfer it to my new residence, I agreed. The transfer was to happen on the 1st of April and I was told that someone from the Gauteng branch would contact me. To date I have had no response. When I called through today, the 15th of April I was kept holding on for 45minutes I was told that the line was canceled and I would need a new line. I asked to speak to a supervisor and the line was cut on me. I am disgusted at the terrible service.
