A Metro Bank customer has told of his fight to get more than £14,000 back after its systems failed to stop a fraud involving the AI chatbot Claude. On 19 June, Metro Bank spotted a suspicious transaction for £90.90 and texted Rutter to ask whether he had authorised it. After Guardian Money got in touch, Metro Bank temporarily refunded Rutter while a chargeback refund was sought from Anthropic. Rutter has since been refunded by Anthropic, and the temporary refund from Metro Bank is due to be taken back by the bank. Anyone who has been affected by an unauthorised card fraud is advised to contact their bank immediately and ask for a refund.
