I would dispute this immediately. From OP's account, the "consultant" either misrepresented or failed to explain what, exactly, the credit card was going to be used for. The "consultant" should have thoroughly explained - verbally and in writing - what he was going to do with the credit card and how much the charge should be. I would present all of the facts to the credit card company and see what happens. If that isn't successful, I would get to a person in charge at Princess and explain what this "consultant" did and what he didn't do. Tell Princess you expect that charge to be reversed.
