I had a similar situation several years ago, I wrote a letter to the State Attorney General, they were well aware of the situation. They had received enough complaints that they filed a class action law suit, I was prepared to go to court in the matter. Fortunately a settlement was reached, I got my gun back but not the money I'd paid for the work. The gun had not even been taken out of the box that I had shipped it in despite claims by the firm that the work had been completed. All I can tell you from my experience is to hang in there these things take time once you get the authorities involved.
