Can I get help on an insurance claim if other insurance isn’t taking fault?

I was driving straight at the posted speed limit approaching an intersection. The traffic light was green, as I reached it, it turned yellow. The other driver ran his red light from the farthest right lane while the other vehicles were at a complete stop and hit me on the right side of my vehicle at intersection. I submitted dashcam footage to other drivers insurance. His insurance(State Farm) denied claim because he said he had a green light. I received voicemail from State Farm saying it was a “he said vs he said” situation. I believe it was an act of bad faith because I submitted evidence to back up my claim and he did not. Therefore it’s not a “he said vs he said situation
