I would begin to get all your ducks in a row. Read through that statute and have everything that you need that is required by the statute. I would then go to an attorney and present him with your 'evidence' and pay for one hour of his time. Ask him for any advice he may have and how you should move forward. It may be as simple as the pawn shop getting a letterhead scaring them enough to give up the games. My guess is they have prepaid legal and have really not retained a very expensive defense lawyer.
