Got a parking ticket in Newport Beach at a meter that I paid for via Parkmobile. Followed the procedure on the ticket to contest and mailed materials to the address they show on the ticket. The FAQs indicated a decision would not be made for at least 4 weeks - so after 4 weeks I called their number (took literally a week of trying to get to an actual person) and she said they never received my contested info and, not that 21 days have passed, I'm ineligible to appeal the ticket, per DMV rules. Nice scam, PTicket - I wonder how many appeals end up in their trash can so they can say they never received it! Moral of the story, contest online or if you have to send stuff, send Certified with Return Receipt.
