BagDrop Seongsu Station Luggage Storage — Cancellation & Refund Policy
Written: 2026-08-02
Operator: Hong&Lee Holdings Co., Ltd.
Service: BagDrop Seongsu Station Luggage Storage (2F, 122 Achasan-ro, Seongdong-gu, Seoul)
Article 1 (Purpose)
The purpose of this Policy is to set out the criteria and procedures for cancellation of payment and refunds in connection with the use of the unmanned luggage storage service "BagDrop Seongsu Station Luggage Storage" (the "Service") operated by Hong&Lee Holdings Co., Ltd. (the "Company").
This Policy complies with the Act on Consumer Protection in Electronic Commerce (the "E-Commerce Act") and related laws, and sets out specific refund criteria reflecting the nature of the Service (unmanned, physical storage, use beginning immediately on payment).
Definition of the point of payment
Payment for this Service occurs up to twice depending on the plan. Under this Policy, "payment" includes both of the following points in time.
| Category | Point of payment | Applicable plan |
|---|---|---|
| First payment (prepayment) | When you place items in the locker | Base plan (4 hours) in full / 24H PASS in full |
| Second payment (settlement) | When you retrieve items from the locker | Hourly excess charges incurred when the initially paid usage time is exceeded during use |
Unless expressly distinguished, each clause below applies equally to both the first and the second payment.
Article 2 (Nature of the Service and Notice of Grounds Limiting Withdrawal of Subscription)
1. This Service is a physical, "use begins immediately" service in which the user is assigned a locker on payment and can store items at once.
2. Under Article 17(2)5 of the E-Commerce Act and its Enforcement Decree, withdrawal of subscription may be restricted for the portion of a service that has already commenced. In addition, for products paid for online in advance, the Company may sell them as conditional products with restricted refunds regardless of whether storage has begun, on the premise of the user's express consent (notice and consent on the payment screen). Specific criteria follow Articles 3 to 5.
3. The Company gives prior notice of the contents of paragraph 2 on the payment screen and in the Terms of Service, and the user is deemed to have confirmed and agreed to this before payment.
Article 3 (Cancellation and Refund after Storage Begins)
3-1. Base plan (4 hours base + hourly excess charge)
1. From the moment the locker door opens and items are placed inside (the point at which the control system switches to "in use"), the service is deemed to have commenced.
2. In this case the 4-hour base fee already paid is not refunded. This is because it constitutes actual provision of a service, in that a specific resource (the locker) can no longer be provided to another user for that period.
3. Any hourly excess charge incurred is settled and billed only for the time actually elapsed at the point of pickup, and no overcharging for unelapsed time occurs (same as the pricing rules in §2).
3-2. 24H PASS
1. The 24H PASS is a flat-rate product usable without additional charge for 24 hours from the time of payment.
2. Cancellation before storage begins (before the locker switches to in use): where payment was completed online, refunds are as a rule not available, in accordance with Article 3-3.
3. Cancellation or mid-term refund requests after storage begins: refunds are as a rule not available. However, cases where normal use was impossible due to reasons attributable to the Company or the vendor (the locker manufacturer/operator) (Article 5) are an exception.
3-3. Non-use after online payment (no-show) — no refund as a rule
1. Where the user completes advance payment through the website, the product (locker usage right) is deemed confirmed to the user at the point payment is completed.
2. If the user subsequently does not visit the site, or does not store items due to a simple change of mind (including no-shows), this is treated as abandonment of use due to the user's own change of mind and the amount paid is not refunded.
3. This article applies commonly to all products payable online, including the base plan and the 24H PASS. (On-site kiosk payment is structured so that storage occurs at the same time as payment and is not subject to this article; Article 3-1 applies instead.)
4. However, cases falling under Article 5 (reasons attributable to the Company), such as where a reservation was not assigned due to a system error, are an exception and are refunded.
Article 4 (Second Payment — Settlement of Excess Charges at Pickup)
This article applies only to the second payment (settlement of excess charges) arising at the point of pickup where a base-plan user has used the locker for more than 4 hours. (The 24H PASS does not involve a second payment and is not subject to this article.)
1. Normal payment and retrieval: where the second payment is approved normally, the locker door opens normally and the items are retrieved, that payment is regarded as legitimate consideration for the time actually elapsed and is not subject to refund.
2. Objection to overcharging: where the user considers that the excess charge billed differs from the time actually elapsed, an objection may be raised through customer service.
– The Company verifies the validity of the amount billed on the basis of the control system's entry/exit logs (locker opening history).
– Where the system logs confirm a discrepancy between the time actually elapsed and the amount billed, the difference is refunded by transfer to an account in the user's name under Article 7.
3. Where the second payment is completed but the locker does not open: where the user's items are inside the locker and the door does not open after payment due to a system error or locker fault, this is treated as a serious matter infringing the user's right of access to their property and is handled as follows.
– Customer service attempts remote action immediately on receipt (within operating hours), and where remote action does not resolve it, the principle is highest-priority response including dispatching an on-site technician.
– No additional charge is applied for the extra waiting time arising while retrieval is delayed, and where fault on the Company's part is confirmed, the second payment already made is refunded in full or separate compensation is considered.
4. Duplicate approval of the second payment: where the second payment is approved twice due to a communication error or similar, the excess approval is refunded automatically or on request as soon as it is confirmed. (Duplicate approval of the first payment is handled the same way — see Article 5(2).)
5. Where the door does not open because the second payment fails: where payment is attempted with a valid payment method but is not approved due to a PG/VAN error and the items cannot be retrieved, alternative means such as manual opening through customer service (remote action) are supported first. Since no payment was actually made this is not subject to refund, but supporting successful payment is the highest priority.
Article 5 (Refunds for Reasons Attributable to the Company — Full Refund + Compensation Considered for Delays)
Where the user was unable to use the Service normally for the reasons below, the Company refunds the full amount paid and, where necessary, considers separate compensation (provision of an alternative locker, coupons, etc.).
1. Where payment was completed but no locker was assigned or the door did not open due to a system error
2. Duplicate payment due to an error in the payment system (PG/VAN) (applies to both the first prepayment and the second settlement payment)
Refunds for the above reasons are, as a rule, processed proactively by the Company as soon as they are confirmed, without a separate claim from the user.
Article 6 (Reasons Attributable to the User — Refund Restricted)
Refunds are as a rule restricted in the following cases.
1. Where the user requests cancellation after storage has begun due to a simple change of mind, without any loss of items (Article 3-1 applies)
2. Where the user completed payment online but does not store items due to a simple change of mind (including no-shows) (Article 3-3 applies)
3. Delay in use caused by the user losing their authentication method such as PIN, QR code or card (however, the Company provides support where it can be resolved by remote assistance through customer service)
4. Damage or sanctions arising from the user storing prohibited items (hazardous goods, perishables and other items prohibited under the Terms of Service) at their own discretion
5. Refund requests for flat-rate products such as the 24H PASS made solely on the ground that the actual time used was short (Article 3-2)
Article 7 (Refund Procedure and Timeframe)
1. Refund request: submitted through customer service (phone / KakaoTalk / web chat) or a website enquiry. On submission, payment details (order number, last 4 digits of the card, date and time of payment) and refund account details (bank name, account number, account holder) may need to be confirmed.
2. Responsible party: refunds are handled directly by the Operator (the Company); the vendor (World Locker) only forwards the details received to the Company.
3. Processing timeframe: processed after the grounds for refund are confirmed. The time until it is actually reflected depends on the actual approval-cancellation processing time of the payment method concerned (card company, etc.).
4. Refund method: partial refunds are not supported, and refunds are processed by transfer to an account in the user's name. Account details (bank name, account number, account holder) are confirmed when the refund is requested.
Article 8 (Customer Service and Processing Hours)
1. Customer service hours: 09:00–23:00 daily (every day of the year)
2. Support is provided in Korean, English, Japanese and Chinese through phone, KakaoTalk and web chat.
3. Refund requests received outside operating hours are as a rule processed the next day. Matters that can be resolved immediately by remote action (opening the door, resetting, etc.) follow the call-centre operating-hours standard (the 09:00–11:00 immediate remote-action window).
Article 9 (Dispute Resolution)
1. Where a refund-related dispute arises between the Company and the user, it is resolved by mutual consultation as a rule.
2. Where consultation does not succeed, the Act on Consumer Protection in Electronic Commerce and the Consumer Dispute Resolution Criteria (notified by the Fair Trade Commission) apply, and mediation may be applied for with the Korea Consumer Agency or the Electronic Commerce Dispute Mediation Committee where necessary.
Addendum
1. This Policy applies from its effective date.
2. The Company may amend this Policy in line with relevant laws and operational needs, and will notify users of any amendment through a notice within the Service or the procedure for amending the Terms of Service.
