Telkom upgrade gone wrong - no feedback after two months

On the 14th of December I went to Telkom Hyde Park to upgrade one of my existing contracts. Instead of upgrading the existing contract, the consultant gave me a new contract instead, even though I did not want one. I, on the other hand, thought that I was signing for an upgrade. I immediately went back two days afterwards to inform them and the consultant aknowledged that he made a mistake. They then logged a ticket for me and told me that they will cancel the contract of the new sim and move it to the contract that I originally wanted to upgrade. However, it has been more than two months now and nothing has been done. I am still paying for an additional contract that I never wanted. I have called Telkom numerous times, I have submitted two complaints on Telkom's website and I've been to the Hyde Park branch 7 times in past 2 months in an attempt to follow up and get this sorted, however nothing has helped. At this point I am hopeless and considering to lodge a complaint with ICASA as nothing is being done. Absolutely terrible customer service from Telkom.
