OKAY so I have a toll bill for a little less than $200 AND THEN they charged me an extra $400 in fees!!! Apparently the bill goes back as far as 3 years! I would have definitely paid the toll if I knew I had the bill. I had NO idea, and was not aware until I received a bill for over $600! WHAT? So as soon as I received the bill, I automatically called the contact number and talked to an agent who then told me to talk to someone over at the DMV to see if they could help me with the problem I was having. After speaking to the woman at the DMV, I called back and I spoke with agent 118 and he was the most DISRESPECTFUL, UNPROFESSIONAL individual I have ever spoken to. He rudely HUNG UP on me after telling me there was nothing he could do. The website says they strive to reach customer satisfaction and I am absolutely 100% UNSATISFIED with 1) the way I, as a human being, was spoken to, and 2) for the fact that they are robbing, and stealing money from Colorado citizens. WOW I am so infuriated by the way this man antagonized the situation and the way this company treats us as residents of Colorado. ZERO STARS.
