Do you have a question? It's not unusual to have the same insurance company represent both drivers in a car accident. If you have an issue with the insurance company, you should speak with an insurance attorney regarding your situation.

As soon as you can get an attorney experienced in insurance law to represent you preferably on a contingent fee basis. If you describe the crash differently from the police report, you are going to have a hard time getting a claims person to adjust your case without a lawsuit withjout attorney involvment.
When you hire that lawyer, make sure you have him understand what happened in the crash using a bunch of Tinker Toy cars. It's easier to show him than to try to describe it with words. I have a hard time understanding you even after rereading what took place. I'd love to see how this crash took place before I tried to represent you.
