I stopped my express pay session to the wrong time, and was charged incorrectly

I stopped my express pay manually in the app to the incorrect time, and I got overcharged 

In some express pay areas, if your session doesn't end automatically when you leave, you can register the actual end time and end the session manually in the app.

Just open the parking session, scroll down, and tap "Stop session."

You’ll be asked to confirm the time you actually left the parking area.

What should I do if I stopped my express pay session at the wrong time and was charged incorrectly?

Make sure to stop the session at the correct time, as you'll be charged from the start until you stop it. Please note that you are responsible to stop the parking to the correct time, and and that you must bear any associated costs.
