How to do it

  1. Call the number on the back of the card, or use the card issuer's app, and ask for a replacement card with a new number.
  2. Go through recent transactions with the issuer and dispute any you do not recognise.
  3. Once the new card arrives, update it at subscriptions and shops where the old card was saved.
  4. Cut up the old card.
