Dude, go get a public adjuster if you're having real problems. My experience is all with property stuff specifically commercial in the construction world, but I would hazard a guess they have PA's that work any types of specific insurance markets.
It's probably pretty damn lucrative for them considering all of the shenanigans with medical billing and what have you, and with it being just a minefield with policy shit, you're better off getting somebody who knows how to walk through it.
The other benefit is you don't have to pay them anything unless they win the claim and they're going to make certain their fee is covered through whatever negotiated resolution there is.
That's just my two cents dealing with insurance companies for the past decade or more. And the biggest thing to always remember is at the end of the day no matter how nice the carrier might be seeming, they're going to try to fuck you one way or the other, and always be the squeaky wheel, because that's the only way you're going to get the grease. They bank on people who just give up, it's the whole the process is the pain deal.
