We maintain strict policies regarding attendance to respect the schedules of our Service Providers.

3.1 No-Show Policy

Failure to appear for your confirmed appointment without prior notice or valid cancellation is considered a "No-Show".
No-shows will result in the forfeiture of your entire deposit. No refunds or rescheduling will be allowed.
A cancellation of a reservation not yet confirmed by the Service Provider is not treated as a No-Show and is fully refunded (see Section 4.2).

3.2 Late Arrival

Service Impact: Arriving late may result in a shortened service duration to ensure subsequent appointments are not delayed.
Full Remaining Balance: If the service proceeds despite your late arrival, you are still required to pay the full remaining balance directly to the Service Provider, regardless of the shortened actual duration of the service.
Cancellation Criteria: If you are more than 20 minutes late without prior notice, your appointment will be automatically canceled, treated as a No-Show, and your deposit will be forfeited.

If a reservation is still pending provider confirmation, a cancellation—regardless of timing, including after the appointment time has passed while the reservation remained pending—will receive a 100% refund of the deposit. Such a cancellation is not treated as a No-Show.

5. Refund Processing & Currency

This section details how your funds will be returned following a valid refund request.

Unauthorized disputes or chargebacks may result in the temporary or permanent suspension of your access to the Platform.
