1. General Customer Support
Email service@radbkao.com for product questions, order assistance, shipping inquiries, return requests, refund questions, or other store-related support.
For an existing purchase, include your order number and the email address used at checkout.
2. Order and Shipping Questions
Most in-stock orders are processed within 1–3 business days after payment authorization. For standard delivery within the United States, estimated carrier transit is generally 5–12 business days after dispatch.
For tracking or delivery questions, include your order number and any available tracking information.
3. Delayed or Missing Packages
If tracking has not updated for an extended period, the shipment appears lost, or a package marked delivered cannot be located after reasonable checks, contact us with the order number and available tracking details. We will review the shipment information and work with the relevant carrier or fulfillment provider where appropriate.
4. Return Requests
Eligible products may be returned within 30 calendar days after confirmed delivery. Before sending merchandise back, email service@radbkao.com with your order number, the product involved, the reason for return, and relevant photos or videos where necessary.
5. Damaged, Defective, Incorrect, or Incomplete Orders
Contact us as soon as reasonably possible if an item arrives damaged, defective, incorrect, incomplete, or materially different from its description. Where reasonably possible, we recommend reporting the issue within 7 days after delivery so it can be documented and reviewed promptly.
The 7-day period is a recommended reporting timeframe only and does not reduce the 30-day return window or limit rights available under applicable law.
If the issue is confirmed, we will provide an appropriate replacement, refund, or authorized return solution without requiring the customer to bear the reasonable return cost caused by the qualifying issue.
6. Refund Questions
After an approved returned item is received, we generally aim to complete inspection within 5 business days. Once an eligible refund is approved, it is issued to the original payment method.
Approved refunds are generally processed within 5–10 business days after the returned product has been received, inspected, and approved. A bank, card issuer, or payment provider may require additional posting time.
7. Order Cancellation or Changes
Contact us as soon as possible after purchase. We recommend submitting cancellation or change requests within 12 hours whenever possible. Later requests may still be reviewed if fulfillment has not begun, but cancellation or modification cannot be guaranteed once processing, fulfillment, shipment preparation, or dispatch has started.
No cancellation fee is charged for an order successfully canceled before fulfillment.
