Complaint Review: Law Enforcement Systems LLC

Law Enforcement Systems LLC sent me a notice for collection of an ez-pass toll violation. I have an account in good standing with ez-pass since 2005. When I tried to dispute this violation online it asks for a 13-digit violation number, but the letter they sent me only has 7 digits in the violation number. I haven't had any luck trying to contact them by phone. When I ask to speak to a representative, it says next available rep will talk to me, then hangs up on me. I think they just want you to send payment without question, and I'm not doing that. I think ez-pass should get on them about this or get someone else to take care of things.
