Telkom does not cancel and bills incorrectly

I was moving premises and called to ask Telkom to move my line and was informed there were no available ports within the area I was moving to and they would call if one became available. They called early Jan to install the line and I asked to cancel the line as I had made another plan, I was told I can't cancel and hounded with smses about a technician coming. A lady called to say the technician was coming and I told her I don't want the line please cancel, she said she would. I was then invoiced end of January for a line I did not have. I called again and spoke to a manager who said I needed to fill out forms (the other 2 staff members apparently forgot to mention this) and then spoke to the accounts department who said they would sort out the account. However Telkom debited the money from my account. I called on 2 Feb and was told they would find the recording and get back to me in 10 days; I am still waiting and have received no refund. Call ***
