No, you're not able to cancel a purchase/transaction after you've authorised it. If you've made a transaction and then changed your mind about your purchase, you would need to contact the merchant/retailer directly. However, if you subsequently experience any issues with the transaction, we may be able to assist.
Please call us on 0800 161 5291 from 8am – 6pm Monday to Saturday. Call charges may apply. We also offer a Next Generation Text or SignVideo service. For more information, visit barclaycard.co.uk/accessibility.
