Shocking treatment to a current good standing client

I just recently app**** for vehicle and asset finance through ABSA. Bare in mind that I currently have a vehicle financed through ABSA and pay them R8200 per month in repayments. I have been paying on time every single month for the past 4 years and there have never been issues with affordability. I was now looking to settle the vehicle through them and re apply for a much much cheaper vehicle with a re payment of only R6200 per month. So R2000 less than what I am currently paying yet they decline my application. Surely they can see on their system that I religiously pay my R8200 every sing,e month so surely I can afford a re payment of R6200 each month. When I called into the department, I spoke to a extremely rude Manager, Moses. He is apparently the manager of the vehicle and asset finance division within ABSA. Moses treated me like ****. They way he spoke to me and treated me was absolutely shocking. This is the service that ABSA offers to their outstanding clients. I would not recommend getting finance through ABSA whatsoever. rather go through wesbank.
