# IA: Duplicate-POP refund — match bank lines before refund - TooCute claimed duplicate callout payment; attached two POP PDFs. - AM reply: both show same payment reference; only one credit on account — ask client to re-check. - Client later sent screenshots claiming two different references. - **Rule:** Never refund on client assertion alone. Match Nedbank/FNB/Capitec lines by amount+date+reference; if one ref credited once, explain single credit; if two distinct credits exist, refund the duplicate to the original payer account (same-account refund). - Do not publish client banking details to KB/export.
