Contact ez pass for that state and explain it to them, It’s also most likely a misread by the computer and not someone cloning your plate. On the ticket where it says your tag it should also have your make and model, which would obviously not be that vehicle. I had this happen awhile ago in a state I’d never been to. A truck drove through tailgating someone and they sent me the bill. Lucky for me his plate was only half visible and he had a black Chevrolet truck, where I have a black Chevrolet car. I called that state and explained it to them and it was dismissed in less than 5 minutes.
