What should a purchase card holder do if they discover that the purchase card account was billed multiple times for the same purchase?

If a purchase card holder discovers that their account was billed multiple times for the same purchase, they should first review the transaction details and gather any relevant documentation. Next, they should promptly contact the vendor to dispute the duplicate charges and request a refund. Additionally, the card holder should report the issue to their organization's purchasing or finance department for further assistance and to ensure proper accounting procedures are followed.
