I cleared this hiccup by sending every required detail in a single message. First, I shared the payment transaction number exactly as it appears on my bank statement. Then I provided the date and time the payment posted, plus a screenshot of my current I-Pass balance display. All of this went through the support page at https://ipass-illinois.pissedconsumer.com/review.html , where I described the unresolved balance. Within 24 hours, I-Pass customer care replied to confirm their system had processed the deposit and my tag account reflected the new funds moments after their update. Offering full payment context and visual proof in one go unlocked a swift correction.
