Condo Open Box OUtside Exposed Cables

We need help getting someone from Comcast to fix our open cable box with exposed wires and cables outside the building. So far, I can't get anyone at comcast to help. Each time a technician comes to help an individual condo unit, they make a mess out of the outside box and the wires and cables are now exposed and the box won't close. We believe Comcast is responsible for cleaning this up. Please let me know how to get someone to assist.
