You bought something in Korea, but the size is wrong, the item is damaged, or you received the wrong product. At the store counter, the staff asks for a receipt, checks the card payment, and explains whether a refund or exchange is possible. This is a common daily-life situation, but the Korean words can sound formal and fast.

This lesson teaches practical Korean refund and exchange phrases for foreign residents, workers, students, and travelers in Korea. You will learn how to understand words like 환불, 교환, 반품, 영수증, and 결제취소, and how to explain a simple product problem politely.
