Property Damage to Irrigation System

Hello, recently Xfinity Comcast buried the service line and damaged our irrigation system. 

The company that services our system has given us an extensive break down and process and cost to repair. 

I’d like to have Xfinity repair the system back to operational level as before and file a property damage report and claim.

This is not the first time Xfinity has caused property damage, and still has not resolved the outstanding issue of exposed junction box that services our neighborhood. Please help.
