Low hanging line across public road

There is no apparent way to report a low hanging line across a public road.  I have hit the line with my RV causing damage to the refrigerator cap.  The line is below 12' clearance.  I have called the sheriff, no help there.  Tried every number at comcast that I have access to and searched the web site.  It appears there is no way to report this.  I guess we will have to wait for a larger truck to tear the line down to the ground before anyone cares.
