Wesbank delays and evades and refuses to provide services that are paid for.

I bought a second-hand Toyota Yaris through Wesbank in 2008. I paid it off by 2012 as per the contract. I have now decided to sell it and I need the ownership papers. Contacting Wesbank has been a frustrating and unhappy experience. To give a brief summary: Their attitude to their customers is arrogant, off-hand and evasive. To speed up the process I paid the fee they were demanding on 30 September by EFT (an instant payment with their reference number). They acknowledged receipt of the payment on 12 October 2022! They delay by asking for information that they have already been sent to be sent again. A few days ago I was asked to prove that I had paid off the car. I was furious at that. They would have repossessed the vehicle years ago if I had not finished paying it off! That does not seme to have occurred to them. Even the auto-response in their emails is insulting: "Dear valued customer, Thank you for your email, kindly note we will respond in due course." IN DUE COURSE?? Most big business auto-replies claim that the customer will be contacted by a consultant within a set period and some businesses even manage to do this. Wesbank doesn't even bother to lie! All I want is for Wesbank to get its money-covered rear end out of its comfortable chair and get me the documents that are mine and for which I have paid. And I would like them by Monday 17 October, or the end of the decade if they can manage that.
