Definitely check your statement. I believe it charges the pax based on the GPS tracking---not on the actual travel through the toll booth. I have had a number of tolls added to the pax's bill just because I got close to the toll. So if the system can misinterpret your location to inadvertently charge for a toll, logic would dictate that it could also make a similar mistake and not charge for one you actually paid.
