Quit wasting your time. Send a statement to the insurance company that you have documented that they are acting in bad faith. Then go to your state's insurance commissioner and tell them you have documented the insurance company acting in bad faith. That term is important; it is a legal definition that gets their attention. It is important that you put the insurance company on notice using the "bad faith" term, and it is equally important that you make the commissioner aware you have accurate documentation.
I bet things change quickly after you do what I have suggested.
At the same time, you may want to consider hiring a private adjuster. They usually charge 10% of the loss, but provide you with an independent estimate of the repair costs.
