After almost a month of returning back to Canada from my trip to NJ, I got a letter in the mail from EZpass for violation that I didn't pay $1 toll fare, so after admin fee it going to cost me $51. I was there for 4 days and we paid every toll we came across, and I believed for this one (raritan toll south), there was no one at the booth so we deposited the $1 of coins into the buckets and left. What should I do, since I know I have paid the dam toll.
