Is this a licensed repair facility? Did they give you a written estimate? If not they are violating the Florida Motor Vehicle Repair Act.
For example, if they failed to give you a proper written estimate, you do not have to pay anything for the repairs (if any), and they may be barred from filing a mechanic's lien on the car.
This is a tricky situation and you need to play your cards in order, or else you may end up in a jam. Consult with an auto fraud attorney, or view my profile on Avvo.
I am an attorney who is only licensed in the State of Florida. My answer is general legal advice based upon what I perceive your question to be, and should not be relied upon because every person's facts and circumstances are unique, and because specific laws vary from state to state. To completely evaluate a legal issue requires reviewing and evaluating all relevant facts, applicable laws and other information. My answer does not create an attorney-client relationship, and offered for informational purposes only.
