I don't blame you, he owes you the money back, he can pay the fees for his "insurance" just like you did. I don't think this guy meant to sell a chariot impeller off as a mull, I think he bought it from someone here selling it as a mull and now he sold it as he thought it was and got "caught". The correct way to do this is option A and say hey I was told it was a mull my bad
