My car needed some repair work. Insurance set me up for a rental with Hertz who told me not to pay for bridge tolls with my own car's transponder. When I take the car back, they tell me I'll be invoiced later for the tolls. Had 4 toll crossings which ordinarily would come to less than $30 (even less if I had used the transponder).

A month later, the Hertz charges show up: $77 (including 'processing fee'). Called and complained. They said they'd look into it. Never heard back.

Not using them again.
