If you had credits in your account, they were likely automatically applied to cover some or all of the cost of the next booking. If you didn’t make a booking or haven’t made a booking in over 6 months, the credits are subject to a dormant account service charge, applying to certain states. More details can be found here.
If none of these apply, something might have gone awry. Get in touch with our customer experience team and we’ll help you get this sorted out. You can chat with us using the icon on the bottom right. We're here to help!
