Incorrect arrear allocation

I am truly annoyed and disgusted by Telkom's service. I relocated last year already February 2019 from Cape Town to Pretoria and app**** for my landline to be moved. I followed up numerous times with no response. Evenetually during the month of February/March 2019 Someone from Telkom came to fix my landline at my new premises, but they never got it to work. I then decided to cancel the Telkom account altogether. I got confirmation that my landline was cancelled and I settled all balances owed. I even went into a Telkom branch to verify that it was closed-to be told I have no active accounts with Telkom.

Now more than a year later, when check my credit records, there is an apparent arrear account with Telkom. I then went back to Telkom yesterday to clear up this mess but the consultant revealed that I owe over R1000 for an unpaid debit order.

I never had a debit order with Telkom to being with, I used to pay via EFT. I also never received any phone calls or letters to inform me of any arrear amounts.

I want this amounts reversed immediately and my credit record cleared up. This goes against the consumer protection act and Credit act completely and therefore I believe I am within my rights to dispute this completely. I received no notices whatsoever about unpaid debits orders and I didnt receive any notification about any arrears or possible credit record listings. If I was aware of any arrears I would have paid it up immediately.
