If a Platform/Payment Provider requires the Company’s verification (e.g., delivery confirmation), the Company may assist the investigation but does not guarantee refunds.

6.4 Billing Disputes; Chargebacks

You agree to promptly report billing issues to the relevant Platform/Payment Provider. If a Platform/Payment Provider requires you to contact the Company, you agree to provide relevant transaction details (e.g., order ID, Platform, date).
