Unfair treatment

Wesbank is requesting a 50% deposit from 200k car, this car is so very lower than my budget as a private bank client with good credit score, they even lie about lower interest rates for private bank client, I got the highest rates possible even though my credit score is good. I'm now thinking of moving my account to another bank. I regret the day I joined FNB as a bank, even upgrading to private banking. Private banking at FNB is just a way of charging more fees, the service is nothing special.
