How far up in managment have you gone? I would ask higher and higher up or just ask for a corporate complaint line.

I have seen a "Jesus is my co-pilot" but never a God is driving bumper sticker..

God didnt drive that truck into you, i would be hostile with my insurance company and not stop until i got what i deserved... ask around for a low budget lawyer even that would help you alot if they have half a clue.
