FNB, assist a faithful customer please

I am hoping that FNB find a way to assist me with an issue I have. I have been offered a personal loan on my FNB app for some time now, and I keep denying it because I don't accept the values shown. They have since improved the interest rate they are offering me, and whilst it is certainly appreciated I still think it is a little high and would like them to review it. I requested a call back in this regard on Monday, and the consultant informed me that because it is personalized that there is probably no way they can. I said to her that cannot be considering there are people who run FNB, and not some autonomous AI system whose rule is absolute. More proof is that I recently purchased a vehicle and after negotiating with Wesbank they improved the interest rate that they initially offered me, which was very decent of them. I have been a customer of FNB/Wesbank for a number of years now, and hold a number of debt instruments with them, as well as having concluded more still. All my accounts are in good standing and always have been. I hope that FNB can contact me to renegotiate the interest rate on the loan as I enjoy banking with the organisation and find them to be very judicious and amicable.
