Anyone who sees suspicious charges on their bill is asked to call WSDOT for a refund

Really?   You know over 3300 drivers were charged double, but you don’t want to auto-refund those people?   You expect people to contact you for a refund?

This is pure laziness, and lack of customer focus.  If you cared about the commuter,  you’d do the work to validate people were refunded.  The company running the tolls should step up.
