downed wire - no service

The Xfinity wire going across a utility easement to the pole where my Xfinity service starts...is down.   It's not on my property, so I cannot see it more than about fifty feet.   I contacted support, but instead on issuing a service request, they scheduled a professional install (!).   I cancelled this appointment.  Nothing needs to be done at my home, just the wire that feeds my service from the adjacent property needs to be repaired or replaced.

Who should be contacted when the Xfinity wire is downed by trees?   At this time I have no service.
