from experience,
i rented a car drove a rout with like 10 tolls, one day i got a bill for $25 max service fee and one toll charge, called and they told me if i send a e-zpass statement for the rentall week showing that i used my pas they will refund me,
since i didnt have that exact charge on the e zpass statement, they charged me for the toll but not the service fee
i hope this helps
