This rating is based on employee behavior.
While driving on the freeway I noticed a truck gaining on me going in excess of 90 miles an hour (I was going 85), he tried to pass on the right almost hitting another car and rear-ending a semi! I put my breaks on yielding to him and waving him to get in front of me since he seemed ready to cause an accident for the sake of speeding. He got in front of me, I shook my head at him for being so reckless and he had the nerve to wag his finger at me!
At that point I took my phone out and let him see me snapping a photo of his company vehicle and suddenly slowed way down.
If this is a sign of the professionalism this company represents it doesn't surprise me this company has a 1 star rating.
