I was charged twice for one booking

You booked one pass, but you see two charges on your bank statement? It sounds like you accidentally booked a duplicate pass at the same place and time. Don’t worry—we’ve got your back. 

Please go.parkwhiz.com/refund and include the Parking Pass numbers noting which one you won’t/didn’t use. We’ll gladly refund “duplicate passes,” those which are in the same location and timeframe.

As a best practice, refrain from tapping the purchase button more than once every 60 seconds. If the screen still appears to be loading and you don’t see a confirmation screen or email, go ahead and try again.
