Within your portal, you can easily manage the credit card used to charge your bookings.
From the homepage
Click your name at the top right of the screen
Select Billing Info from the menu
Whichever card is marked as Default is the card being used to charge your bookings.
To add a new card, complete the required payment fields then click Add Credit Card. If this card should be the card used for your future bookings, make sure to set it as default.
Please note: If you only have one card on file and that card needs to removed, you'll need to add a new card into the system first.
