Korea's deposit culture keeps the booking system honest — and occasionally it keeps your money a little longer than it should. Ninety-five percent of deposits resolve invisibly: refunded on cancellation, deducted from your bill at the table. This guide is for the other five percent, and its core message is about order of operations: almost every payment problem here is fixable, and almost every one becomes harder if you reach for the nuclear option first.

Prevention: the thirty-second evidence habit

Build one reflex and most of this guide becomes unnecessary: screenshot at every money moment. The cancellation policy on the booking screen (it's your contract). The confirmation with its booking number. The cancellation confirmation, if you cancel. Time-stamped screenshots turn every later conversation from your-word-against-theirs into a ten-second lookup. Second reflex: expect the card statement to look strange. Korean charges often post under a processor's or platform operator's name rather than the restaurant's — an unfamiliar merchant string is not by itself fraud, so check it against your booking history before panicking.

Problem one: the refund that hasn't arrived

You cancelled inside the free window, the app says refunded, your card says nothing. Breathe: refunds to foreign cards normally take several business days — figures around three to five business days are typical — and then your own bank can sit on it until the next statement cycle. Korean public holidays pause the clock too. The checklist: confirm the booking shows as cancelled/refunded in the app, count business days not calendar days, and check pending transactions, where refunds sometimes surface before posting. Past a full week with nothing, contact the platform's in-app support with your booking number and screenshots — that channel exists precisely for this, and written trails beat phone calls across time zones. One more nuance for the detail-oriented: currency conversion happens twice at different moments, so a refund a few cents or dimes off the original charge is exchange-rate drift, not theft.

Problem two: the deposit that didn't come off the bill

Remember from the CatchTable guide: many deposits aren't fees but prepayments, deducted from your final bill. The failure mode is simple human error — a busy register forgets the deduction and charges the full amount. The fix is geographic: it is ten times easier at the counter than from another country next week. Make checking the receipt before you pay a ritual at any deposit booking, and if the number looks whole, one polite line settles it: 예약금 냈는데 확인해 주세요 (ye-yak-geum naet-neun-de hwa-gin-hae ju-se-yo) — 'I paid a deposit, please check.' Staff fix this without drama; it happens weekly everywhere.

Problem three: the charge you believe is wrong

Double charges, a fee after a valid cancellation, an amount that doesn't match the policy you screenshotted. Escalate in this order. First, in-app support with your evidence — platforms reverse clear errors routinely. Second, if a restaurant charged directly, one calm DM with your screenshot: 안녕하세요, [날짜] 예약 관련 결제에 착오가 있는 것 같습니다. 확인 부탁드립니다. ('there seems to be a payment error regarding my booking on [date], please check'). Only third — after those channels genuinely fail — your card issuer's dispute process. A chargeback is a working tool, but it's a last resort for a reason: platforms treat disputed charges as account-level events, and you'd like your account alive for the next trip. The order matters more than the outrage.

Problem four: the no-show fee that wasn't your fault

Flight delayed, taxi trapped, you missed the booking and the policy did what policies do. Total honesty: the restaurant is contractually in the right, and nothing obliges them to refund. But Korea runs deep on 정 (jeong) — human goodwill — and a sincere, evidence-attached appeal wins mercy more often than you'd guess: 안녕하세요, 비행기 지연으로 예약 시간에 도착하지 못했습니다. 정말 죄송합니다. 혹시 예약금 일부라도 환불이 가능할지 여쭤봅니다. ('my flight was delayed and I couldn't make my reservation, I'm truly sorry — might a partial refund be possible?'). Attach the delay notice. Accept the answer either way with grace — and if the answer is no, book them again next trip anyway; that's what the deposit was protecting.

Verified as of the date above. Part nine of the Tables & Booking key — the companion to the deposit rules in the CatchTable guide and the cancellation mechanics in the hunting guide. One guide remains to close the key: the meal Korea forgot to schedule — breakfast.
