FNB Private Bankers: Excellent @ Upselling FNB products. No time for support services

Getting timely support from private bankers is an extreme sport at FNB, yet we are paying for this service. I was advised to make any finance-related applications (vehicle, home, Solar &&&) via the FNB app for better rates and possibly some ebucks rewards. I made an application via the app last week and got rejected for this “specific” vehicle I wanted to purchase. However, an external party (a dealer) gets approved by my bank and then rips me off( horrible interest rate) on an application I made but my bank rejected it. FNB + Wesbank = Same Group. Could you explain what kind of *****edness this is? Where is my private banker when needed? Nowhere to be found!!!!!
