Wesbank won't update my ITC after I settled my vehicle

In 2016 I financed my vehicle with VW(subsidiary of Wesbank) in July I paid up the vehicle.. I was told it will take 30days to update on the ITC. It showed as closed on the ITC, In September I tried to apply for a new vehicle and to my surprise I was declined. I enquired what was the reason for being declined and I was told Wesbank has not yet updated the status on my ITC, even though appeared as closed but it still showed I'm in arrears and that doesn't appear as being paid up.. For two months I have been calling wesbank and they take you back and forth with VW finance until a friendly lady Courtney escalated my matter, I was assigned a gentle man by the name of Percy Robert, he wrote me an email telling me he had been trying to call me but I didn't have any missed call, however I responded immediately to the email and provided him with what he had requested. Until now he has been quite, I called a lot of times spoke to Lindo, Thando, Daniel, Mahlori and lastly Cliffton all of them told me they would send him asn email to get back to and till now no response. My work, my child depends on transportation and now I'm immobile because wesbank is toying with my life, all I want is for you to update my status so that I can get a new vehicle. Worse part is one of their agents said If I was to use them again I will easily get approved of which I feel like it's a conspiracy.. You ruining my life and my credit status.
