Nothing works

I submitted a credit record dispute via their website, and was supposed to be contacted by their call centre within 48 hours (according to the website). It's been more than a week with no contact, so I followed up by calling the call centre. The call centre menu options all dead-end in an automated message, with a warning that unless I return to the previous menu item the call will be terminated. When I finally got through to a living human being, I was told that I had reached the wrong department, and that I needed to call the call centre number again. When I asked to be transferred to to correct department the call centre agent (Kabelo) told me that this was not possible, and then went quiet and refused to talk. I waited for several minutes, and finally ended the call when it became clear that he was determined to waste as much of my airtime as possible without helping me. This is not the first time that I have tried to register a dispute with TransUnion and been ignored, and when I finally managed to register the dispute they terminated the investigation without resolving it because they claimed that I had not submitted the necessary documents - this was after I had spoken with a call centre agent who confirmed that the documents had been received and nothing else was required from my side. The sheer level of incompetence in this organisation is beyond description. They only do the minimum that they have to by law, and will duck and dive and lose documents and not return calls or respond to emails, until the consumer gives up in the sure knowledge that it is just not worth trying to continue.
