Dangerous driving

I was cut off by one of your contractors at a construction lane merge. License plate Utah G50 4XP. This happend near Salt Lake City on Legacy Parkway. He then proceeded to travel at speeds over 100 MPH!! Cutting off other people erratc lane changes. His truck had signage for being an authorized Comcast Contracor and an Xfinity signage as well. The only description I can give of the driver is he had a large grey/white beard. This happened around 5:45 MTN time on 3/26/2026. I hope you are able to track this person down and take appropriate actions.
