Not the PA Turnpike...but...

I was going to Richmond, VA for an event many years ago. I took the DC Expressway, which recognizes EZ Pass. I drove down to Richmond and drove back to Pittsburgh using the DC Expressway.

I got a letter in the mail stating that I did not have an EZ Pass and was billed a higher rate for the DC Expressway and fees for manual processing of my license plate. I contact them, gave them my transponder number and told them that I drove on the DC Expressway twice - my transponder was picked up by their system and billed properly once, but somehow their system missed the transponder the second time.

They waived the additional fees, but still forced me to pay the higher rate for the DC Expressway.
