Tolls by Mail and the customer support around it. Got one in the mail a few weeks ago even though I have EZPass. They include a pic so I know a '1' was mistaken for a '7' which made it my match my plate. For one, I got my plate a few days after the scan date, they are brand new plates, so there's no chance they were even on the road at the time. Seems like the system should know that. The given choices for resolving are: - Mail the slip back with a reason checked. None of the options fit the scenario, there's no "Other". Postage is not prepaid, I have to go to the post office because I haven't needed a stamp since 2012. - Call a number, which I did. I waited 45 minutes on 2 different days, never got through. There is no email address or contact form the website. There is no way to make a dispute electronically. (I guess this part is more like a lack of tech that made life worse for me) The hold message said "EZPass customer services will be with you...". I have an EZPass account which the mistaken plate is on, but wasn't at the time because I didn't have the plates yet. So I figured I'd try the support system through that account, even though it's technically separate. The only option there is a support contact form. I had to type that up twice because, of course, my login timed out by the time I hit "submit" and all my text was lost, an possibility I'm fully aware of as a web dev, but I haven't experienced in like 10 years. That was a week ago, still haven't heard back. Now I'm going to mail thing in with a handwritten choice and can only hope it's going to work out and not lead to some kind of worse mix up that cost more time or money, or flags my license somehow.
