Complaint Review: Nation wide insurance

I was on my motorcycle splitting lanes (which is legal in california) and i was hit by a guy driving in the

 diamond lane while  he was alone in his car, (diamond lane is 2 or more per car) he is insured by nationwide.

He admitted to be the one at fault over and over. When it came time to give a statement over the phone to Gina from nationwide, she asked me if i got a police report or any statements from any witnesses. I told her no i did not because Douglas the guy who hit me admitted to be the one at fault. Well up until  then  nationwide

was treating me good and getting things done as in sending  over a person to  see the damages to my bike and getting things worked out. And yes no matter what  get witness statements and police report i found not everyone

is as honest as they appear to be. After i gave my statement i never heard any thing. So i called Gina the person handling my case and she said Douglas is now saying it was my fault. So i took him to small claims court and listened to his lies in court but the courts found him guilty.  After that i recieved a phone call from nationwide

about settling the case for the amount the court issued to be paid. Which was far less then my damages were

to my bike and equipment i wear. After i recieved a check from nation wide i think all this  crap is over with until I get a letter in the mail from a collection agency trying to collect 2,686.00 for nationwide insurance.They only paid me 2,550.00. So now i have to deal with  this  garbage. I wonder  what is next?. Nationwide and there employees should be  in jail for having there client lie on the wittness stand and fraud.
