A cancelled shopping order and an updated card statement are two records to reconcile. Atomy Korea’s guide notes that card-cancellation results can vary with the card issuer. An unchanged app display alone does not establish that the merchant failed to cancel the order.
Match the exact transaction
Open the order details, the original payment notification and your card transaction history. Compare the order reference, payment time and amount. Where available, use the approval reference to distinguish similar transactions.
For example, imagine two orders for the same amount on one day. If you cancelled the morning order but are inspecting the afternoon payment, the amount will look right while the transaction is wrong. This is an illustration, not a report about an actual customer.
Ask each organisation a specific question
Ask Atomy: “Has cancellation been processed for order [reference]? What date and payment transaction does the cancellation relate to?”
Ask the card issuer: “What is the status of the reversal for this approval reference?” Use its official app or contact route rather than a number in an unverified message.
Do not send a full card number, security code or one-time password in a public enquiry. The aim is to match records, not to disclose payment credentials.
For a return after delivery, keep the stages separate: requesting a return, collection and refund handling do not occur simply because one button was pressed. The Korean guide describes refund processing after collection.
No fixed card-app update period is promised here. Record the merchant’s confirmation and the issuer’s response. If only part of an order was returned, also check whether a replacement charge for the retained goods is part of the agreed process.
