During the rental period with this company, some toll fees were not settled through the rental company but were instead billed to the address on the driver's license by the toll department. We incurred a toll fee of just over $3, which the rental company did not settle for us. The bill was sent to an address in our home country that we do not frequently stay at. Each time the toll department sent the bill, it added additional fines, and by the time we saw it, the fine had increased to $100. We resolved this by negotiating via email with the U.S. toll department, which finally waived the fines. This kind of issue does not happen with other large rental companies and is very prone to causing problems.
