Bad Service

I am deeply disappointed with the service that I experienced from ABSA Vehicle Finance. My acc no is *** and I have been paying every month. My problem started when I wanted to refinance my existing finance after 2 to 3 weeks being approved and it was declined due to long oustanding debt in my ITC profile. My question is how did my finance application got approved in the first place was it because it was December month? I accepted that after being told that i must settle my long overdue account and I did that and just 2 days ago I app**** then my application was declined after sending all documents with the proof that the account was settled and again I am being told I am behind on my current account that I paid on the 30/03/2023 and send the proof of payment that I paid refer ref ***9 after being called that my is in arrears. I feel that ABSA did not treat me like a valued customer. I feel like I deserve an explanation with my application on why was it declined. Currently my salary is better than what I used to get but still my application is declined.
