Difficulty in cancelling Telkom account

I had a Telkom fixed ADSL line at my previous house. Before I moved, I informed Telkom within the 30 day notice period before moving that I am cancelling my Telkom line. I did this in December 2015 so the line should have been cancelled by 1 January 2016. I have since received Telkom accounts monthly. All attempts to contact Telkom to follow up on the cancellation are not addressed from Telkom's side. I also received messages from Telkom stating that they will take legal action if the outstanding amount to them isn't paid. After making contact with Telkom during February 2016, I was eventually informed that the last bill Telkom sent me was actually due by me regardless of the cancellation of the line. After paying the bill, I got an SMS from Telkom saying they incorrectly billed me and I need not make the payment. I again spoke with an agent on Telkom's \chat\" service who again assured me that I will not get another Telkom account, however, three weeks later I did receive another Telkom account. Never, ever, do any business with Telkom if at all possible!"
