Telkom Should be Blacklisted

I cancelled my Telkom account on 29 December 2017. For more than a year I have been struggling to actually get Telkom to cancel my account. Eventually on 13 May 2019 I received a final acvcount with a ZERO balance. Today, to my utmost horror, I found out that I have been blacklisted by Telkom. I do not know when this happened. I have seen on My Broadband numerous articles about people complaining about cancelling their accounts with Telkom. I would like to know why the Cedit Agencies do not blacklist Telkom for false information. If they know that Telkom gives false information, why do they not stop Telkom. Now we as consumers must suffer because of the incompewtence of Telkom

I am highly, highly disappointed.
