Geico Poor Service will give you the runaround Nationwide

I got hit by a drunk driver.  He did about 5,ooo worth of damage to my car but totaled another vehicle.  He did not have enough insurance so I had to file a claim with Geico, my insurance company.  They gave an initial low ball estimate that did not even have the correct parts listed.  The body shop sent them a supplement to correct this.  After several days with no response I finally got ahold of the adjuster who stated he never got the supplement.  I sent him the email that showed it was sent a week ago.  He then sent an email to the bodyshop to set up a reinspection but never showed up.  I called the adjusters supervisor who had no answers as to why this process is so hard but assured me someone will reinspect the vehicle tomorrow.  Very poor service, just giving me the runaround.
