Hazardous orange drop still on lawn after almost a year

I have a Xfinity tech that came in to put in a drop last year because my home was having upstream/downstream issue as he said. To resolve the issue the tech installed a drop what seemed like from my neighbor's line to get me connection into my home. He mentioned its temporary and there will be someone coming in to bury that line. When no one came in at the time specified, I went ahead and gave customer service a call, and they scheduled a tech to come in again and they said the same thing. Again no one showed up, and I forgot about it. Recently my father was mowing the lawn and tripped on the line and almost smashed his nose on the curb. Who do I contact to actually get someone to make a permanent solution for the internet? It looks very off, looks like a extension cord that's just laying there.
