The handling fee deducted when completing the tax refund in myeongdong.

I saw it too late, but I'd better reply. In fact, when you go to Woori Bank, you need to go through the formalities of cash tax refund. In order to facilitate passengers, the Korean government has set up several tax refund locations in the center of Seoul, and can only refund taxes in cash. You must have got the cash for tax refund at that time, but after completing the tax refund procedures at these locations, the Korean government can't really confirm that you left the country with these things, so at this time, your credit card will be traded first. To put it bluntly, the tax refund cash you got at that time was the credit card money. When you go through the tax refund formalities at the airport tax refund window, you can ask the customs to stamp your tax refund form, thus completely completing the tax refund formalities. It's all the same tax refund, but your tax refund procedure is to get the money first and then stamp it, while at the airport, you just stamp it first and then get the money. But you said at the airport that there were no goods that needed tax refund, and your tax refund form was not stamped and handed in. After the specified time limit, South Korea will think that you have not brought the tax-refundable goods out of the country, so you can't enjoy the preferential tax refund options for foreign tourists, and will withdraw your frozen funds again, which is equivalent to the original price of the things you bought, and you have not enjoyed the preferential tax refund. Although it took a long time to reply, I hope I can help more recognition.
