If you see a transaction that you do not recognise, you should contact Customer Services on 0330 808 0102 straight away. If, after discussing the transaction, we believe that it was not authorised by you, you will be refunded as soon as possible, and we will investigate on your behalf. We may need to cancel and replace your card for security reasons. If we need to do so, you will not be charged for a new card and your remaining balance will be transferred across to the new card.
