Yes, I was charged on my own transponder and have the reports to show it. But I'm concerned they won't accept it since my transponder was set up with a 'phantom' vehicle and license plate since we don't have our own car in the U.S.

When I set it up, the guy at the O-Pass office said to just use one of our vehicles from Denmark in order to have something registered - so on the account it reflects that we're driving my Saab with a Danish license plate number (which I don't even own any more). So there is no proof that the rental car was actually the car that went through the toll lane with our transponder.

What's odd is that we used nowhere near $43 in tolls during the trip. Does anyone know if it's possible to get a detailed accounting of the amount so I can see where we were charged?
