Spotty internet due to downed wire. No one has come - XFinity

My internet is going in and out. A truck crashed into the Xfinity cable line at my apartment building 3 weeks ago and pulled the line down along with a bunch of bricks. Several of us have been calling Comcast repeatedly and they have not sent anyone. I work from home and need reliable internet. Not only that but the wire is hanging down in a dangerous manner and the building had to put orange cones out to keep people from getting hit in the head. The wire is literally swinging in the wind.

Yesterday, I called Comcast again and they promised a special tech would come today. Today I called and they said nothing was scheduled. Now they are refusing to send anyone until at least Sunday. I'm losing faith and I'm worried someone is going to get hurt. I am considering canceling and getting DSL.
