Complaint against a Comcast Xfinity driver

Late last week at 4:20 p.m. (likely Jan. 29 or 30) I was driving east on Monmouth Avenue in Highlands, NJ. I came to a four-way stop intersection with Locust Point Road. I came to a full stop as a Comcast Xfinity van [Edited: personal information] on Locust Point Road pulled up to the stop sign. As I was fully stopped and the van was not, I pulled forward to pass through the intersection. But the van simply rolled through the stop sign and cut me off. I slammed on the breaks and threw my arms up in surprise and frustration. The driver looked at me and gave me the finger as he continued through the intersection. After rolling through a stop sign and cutting me off, he had the audacity to essentially tell me to [Edited: "Keep it clean"]. I am a Comcast Xfinity customer and would terminate my service if I could convince my wife. These drivers travel in bill boards for the company yet do not care about their behavior at all. That tells me all I need to know about their supervisors and the company as a whole.
