Inform a credit card company of unknown charges

If there is an error on your credit card statement, you should notify your credit card company as soon as possible and can use this document to do so. This letter is only appropriate for use where your card is still in your possession, i.e. it hasn't been lost or stolen, but there are unknown charges on your account. It is good practice to send this letter by recorded delivery post and keep a copy for your records, so that you have evidence of your correspondence with the credit card company.
