Unfair Treatment from ABSA

I have been an ABSA client for more than 20 years. I am currently having a study loan with ABSA from 2022 when my child was doing his first year at Varsity College. Currently my child is doing his last/fourth year in the same institution, I tried to apply for a study loan and my application was turned down. My problem is that other banks has approved my study loan but my own bank decline my application. N.B. Because of avoiding too much administration in terms of repaying the study loan, i am left with two options : 1. Cancel my account with ABSA due to unfair treatment 2. Move my account to the bank that has approved my study loan
