Fiber line left above ground

I had fiber internet service installed on 9/20. At the time, the tech said he could not bury the line, but that a team would be out within a week or two to bury the line. No one has come. I have called multiple times and they have sent a tech out twice, but they just say a team has to come out to bury it. It has been almost 6 weeks now that I have a line lying on top of my grass. I have kids that play and run through my yard which makes this a tripping hazard. Halloween is in 3 days where we will have more than 10000 people that will be trick-or-treating here who could trip. Not only that, they left the top off the box that holds the equipment by the road. If a kid trips in that and gets hurt in my yard, I will be held liable. This isn’t right. I need this fixed as it is a hazard. It also makes yard maintenance difficult.
