State effin' Farm

Remember, you are the claimant.
You need to contact the person who hit you and basically threaten to sue them. Remind them that State Farm didn't hit you, they did. If you're not made right, you'll go to court.
I would also consult with an attorney.
I've dealt with State Farm in the past and their SOB's but they've had their asses handed to them a lot in court.
State Farm only wins if you let them, you have to be assertive and don't let them take you for granted.
