No worries! All you have to do is log in to your account, click on the card that was lost or stolen, and click the "Report Card Lost or Stolen" button. That card will be deactivated immediately.
If it's a virtual card, we'll be able to issue you a new number. If it's a physical card, please request a new physical card.
