Person contacted me to work on car. Which was originally suppose to have money for by december 2019 and i acquired october 15th 2019. Finally the customer comes up with a downpayment in march 2020 which was under a signed auto order. Which stated if customer decides to cancel the repair order they must pay the total bill of the repair order. Customer has spammed me acting crazy. Is now wanting to press gta charges. And the work order has not even made it to the date the car would be complete. Do i apply for mechanic lien or what steps shoukd i take?
