usa – Has anyone received emails for toll violations from the CVM? Citations and Violations Management?

I got an email from CVM stating that I didn’t pay a toll. I was told the bill was $106. When I logged onto their website there was an administrative fee attached to it of $50 making the total $156. I tried calling the number provided but nobody picked up. I emailed them stating that I wanted to dispute the ticket but only received emails back stating that I needed to pay. As I was traveling in California I did log onto THETOLLROADS.COM and pay my toll usage manually as was instructed by the car rental agency so that is what made me very skeptical of the email. Anyway, I’m still trying to figure it out. Anyone have any suggestions?
