Impossible to get the help needed

In June of this year I cancelled my Telkom service, online, as I was moving. NO mess, NO fuss. In mid-June I received a call where they promised to install lines at my new premises. Which by mid July had not happened.

I then called and called and called Telkom from my cellphone. I was told repeatedly that their systems were down and they could not assist me. Eventually I spoke to a consultant and requested that they cancel ALL my Telkom services. By the end of the conversation the consultant promised that all my services would be cancelled and a manager would call to confirm (I'm still waiting for that call in November)

Since then I have repeatedly emailed and tried to call. I have reference number after reference number since July and still nothing has happened. I now owe Telkom money for a service that was running at a property that I have not lived at for 4 months and that I have not made use of.

I called again today and when finally put through to the manager, the line went dead. I have now run out of options as to what I must do to rectify this problem.
