Telkom opens new ADSL account on old user's name

On the 26th of June, I cancelled both my Telkom ADSL and phone lines as I was moving house. However, I continued to receive bills beyond the period of cancellation. On calling the call centre, the agent was extremely rude and refused to take the reference number for the call in which I had cancelled these services, only to say that (1) I had not cancelled my phone line and (2) that a NEW ADSL line had been opened in my name. Firstly, I definitely cancelled my phone and ADSL at the same time. Secondly, I did NOT open a new ADSL line. I think perhaps the new owner did and Telkom erroneously used my details for the account. I was extremely upset with the very poor service I received. When I asked the call centre agent to speak to a superior, she refused. I also asked if Telkom could review the recording of my original call, as I have the reference number (AI***), and again she refused. The agent was belligerent, rude and unhelpful. I am not likely to install Telkom at my new home as a result of this poor service. I would appreciate if someone would contact me to sort this issue out.
