New Jersey Ez Pass review: Admin fee

My wife and I drove through New Jersey to pick up our kids from college for summer vacation. We took the turnpike and got off at Exit 18E. This was on April 28, 2022. On June 13, 2022, I received a "Final Notice of Enforcement Action" which said I owed $6.65 for the toll, and $50 for "Administrative Fee". There was no explanation of what this administrative fee was for. This was the first and only notice I received. In trying to pay my toll and get clarification of this unfounded fee, I was unable to obtain any direct contact with anyone either on the phone or through the website. I succumbed and paid the full amount of $56.65 for fear of further unjustified penalties. However, someone needs to address the extortion being unjustly enforced against citizens who use the New Jersey highways.
