As a precaution, you should freeze your card on the Card settings menu while you investigate.
Just click on “Freeze card” and that’s it. While your card is frozen, no transactions will be allowed.
Also, you’ll be notified if someone attempts a transaction using your card while it is frozen. Please be aware that even the payments for any subscriptions you may have set up will fail if the card is frozen.
As soon as you notice an unrecognized transaction, please call +1 (515) 859-8338 (US) or +44 203 893 3228 (UK), or contact us at firstname.lastname@example.org so we can investigate further and help you the best way we can.
