Unsatisfactory service from ABSA Vehicle Finance

I have purchased a Venter trailer more than 20 years ago through ABSA vehicle finance / Bankfin and it is paid up. I have tried to get hold of the documents for change of ownership but ABSA cannot / will not help me... ABSA stated that I must pay a "non-refundable" amount of R325.00 to enable them to get the documents. I am not prepared to pay ANYTHING seeing that I have never requested the documents and now that I am trying to obtain the documents, they "cannot find any records". I have corresponded with them on e-mail but I cannot get ANY satisfactory response from them and I struggle to register this trailer on my name.
