Absa wrongfully put unpaid 9 months owed for vehicle

I logged a complaint about Absa, specifically their vehicle finance division about 2 months ago. They have listed my vehicle account as overdue and unpaid for 9 months when I have been paying through debit orders all this time. In the past two months I have sent proof of my bank statements as well as proof of payments for the months in question. I hadn't received any feedback though I had been calling in the past months. It was only last week that I got some feedback, not constructive though. I was told that my account along with a few other customers had an error of having some paid months not be picked up by their system, the ridiculous part is that I was told the manager that can assist me is on leave! Absa are you saying I'm held ransom at the hands of one employee? what happened to delegation? I have been patient enough. This has affected my credit score drastically and I have had 3 failed bond applications because of this bad listing. I am taking this further to the Ombudsman.
