Information to Include
To help us review your request efficiently, include your order number, the email address used at checkout, a clear description of the issue, and relevant photos or videos where appropriate.
Orders, Delivery & Tracking
Most in-stock orders are normally processed within 1â3 business days after payment authorization.
Estimated standard U.S. carrier transit is generally 5â12 business days after dispatch.
Available shipping methods and applicable charges are displayed during checkout.
Orders may be fulfilled through our own operations or appropriate fulfillment partners depending on inventory availability and destination.
When tracking is available, allow approximately 48 hours after shipping-label creation for initial carrier activity.
Delayed or Missing Packages
If tracking has not updated for an extended period or an order is significantly outside its expected delivery range, email service@quandbx.com with your order number.
A carrier status marked âDeliveredâ does not automatically prevent you from asking us to review a parcel you cannot locate.
Returns & Product Issues
Eligible products may be returned within 30 calendar days after confirmed delivery.
Contact Customer Care before sending merchandise. If approved, we will provide the correct return warehouse address and return instructions.
Do not automatically send merchandise to the business registration address.
Preference-based returns are generally returned at the customer's shipping cost.
If a damaged, defective, incorrect, incomplete or materially misdescribed product is confirmed, an appropriate solution will be provided without requiring the customer to bear the reasonable return cost caused by that issue.
No separate restocking fee is charged for approved eligible returns.
Refunds and Order Changes
Once an approved return reaches the designated return facility, inspection is normally completed within 5 business days.
If approved after inspection, the refund is issued to the original payment method within 1â3 business days.
Payment providers may require additional posting time.
Order change or cancellation requests should be submitted within 12 hours after purchase.
Requests cannot be guaranteed after processing, fulfillment, shipment preparation or dispatch has begun.
No separate cancellation fee is charged merely for submitting an eligible cancellation request.
Payment Assistance
Payment methods displayed during checkout may include major credit cards, debit cards, PayPal or other supported methods enabled for your location.
Transactions are processed in United States Dollars (USD).
