To end your Pro plan, log into the app, go to "More" on the menu at the bottom of the screen, then choose Wallet, tap on "Plan," then "Switch to the Pay-as-you-go plan." You'll stay on the Pro plan, keeping the lowest toll transaction fee until the month-end date of your Pro plan. You'll then be switched to the Pay-as-you-go plan and once your account balance is $0, we'll use your credit card on file to start paying your toll bills.
