Ridiculous FNB home loan interest rate

I am presently banking with FNB private clients and recently made a home loan application on the FNB App. I got a pre-conditional offer from the FNB home loan pricing department with an interest rate of 0,40 % above the prime lending rate. I then informed the consultant dealing with my application( Cornell) and my private banker that their offer is unacceptable and informed them about offers that I received from other banks. The best offer was from a relatively small bank with 10,25 % interest rate with a 10 % deposit. The second best offer was from another Major bank with an interest rate of 10,33 % with 100 % bond.

After informing the consultant, FNB made an offer similar to the best offer I have received! I then queried the issues about my application that were concerning to FNB as I have an excellent credit profile, low debt to income ratio and I handle my account very well. Unless FNB can explain their reasons for such ridiculous offers, I m now convinced that FNB uses racial quota when offering an interest rate on Home loan applications.

For the record, the interest rate initially offered by FNB was the highest amongst the five approval I received and it makes me wonder why. I will definitely be moving my personal account to another bank if I don't receive a satisfactory explanation, not the general statement.
