Account settled still not closed by Telkom

This is the second time that I am writing a report on Hellopeter regarding the same incident with Telkom that has still not been rectified. The first time around, after months and months of trying to cancel my Telkom landline at a residence where I lived 1 and a half years ago, Telkom kept charging me on my ADSL landline account for 6 months even though I had cancelled after the first month of moving from that address. Eventually, I had received a cancellation form that I had to backdate and send back along with my ID to have this account closed. At this stage I had already been handed over, because I had refused the pay for the months I was charged since I had already cancelled this line and asked for it to be closed months before being handed over. Still this cancellation process took and eternity, I was not hearing anything back from the Telkom agent who I had been in contacted with regarding my back dated cancellation form, and all the while I was receiving threatening phone calls from the collection agency to whom this account was handed over. EVENTUALLY I received a call from the collection agency saying that the account had been adjusted by Telkom from the over due amount of R1403 to R184.82, and that I only needed to pay the R184.82. I was very pleased and made a payment of R185 and sent the proof of payment to the collection agency, P&P Attorneys. They confirmed with me that they have received the amount and that the account will be closed. I withdrew my credit report from the internet this morning, and STILL the overdue amount of R1403 is reflecting on my credit report, which is negatively impacting my credit score. It is so unfair that the mistakes Telkom made in billing me and not cancelling my ADSL line when first requested is now my problem and I have to now deal with it. It seems the only way to get a response from Telkom is through Hellopeter, since that was how I got someone from Telkom to contact me in the first place after this account was not cancelled. Please Telkom, sort this out for me so that this issue that has been dragging on for almost 2 years now can be rectified and closed.
