4 months is a very long time. Maybe they forgot to charge the admin fee at first. I wasnt charged for the tolls at the time of the rental but 2 weeks later I got a bill/cc charge for $5 or 6 bucks for tolls. Then 4 days later another. Then a week later a final charge. The number of tolls was accurate but each bill had its own admin fee. I wondered if they had split it up to collect more money but I was told it was split up by the days I ran the tolls ( 3/10 -2 tolls 3/11-1 tolls ect.)
