Legal Question in Banking Law in Louisiana

I suspect the agent may have been lying to you, as banks don't disclose bid amounts to competing bidders. In any event, even if the agent was telling the truth, there is nothing you can do about it unless you can prove that they took the lower offer due to some suspect classification like race, color, religion, sex. If they took a lower offer because the other party had better credit, or for other legitimate business reasons, such is their right. In fact, that happens often. The lowest bid is not always the "best" bid because a higher bid is a much better risk. If you were extending credit, would you prefer to extend it to Donald Trump at 3% or some kid down the street at 4%?
