Complete incompetence has had serious consequences for me.

I tried to close my Telkom account during December effective 1 January, 2018 because I relocated to a gated community. However, I still received invoices. After receiving a letter of demand I went again on the 28th of March and filled in a form with the assistance of a consultant. He advised me to put down the requested date of cancellation as 1 January, 2018. Since then , Telkom has reported me to the credit bureau which has caused me serious problems. In an effort to clear my name as soon as possible, I paid the monies outstanding for January and, just to be safe, February as well. My my account is still not completely closed and I apparently still owe them. I have called numerous times in order to try to resolve the issue. This is completely unacceptable and beyond ***********.
