Your spot is confirmed when the game appears under Profile → My Bookings and you get a confirmation email.
Name on the roster but no confirmation yet? Your payment is still processing, which takes a few minutes. If it fails, you'll get an email, your spot is released, and you can book again with the same or a different card.
Pending or double charge? A pending amount is usually a payment that's still processing, or a failed attempt that will drop off on its own. If you see two completed charges for the same game, message us with the facility, date and amounts.
Your name disappeared from the roster? Usually the payment didn't go through. If the game itself changed or was canceled, we'll have sent you a message.
