Once your claim is reviewed and approved (typically within 3 business days), we will offer one of the following at your choice:
Orders may be cancelled for a full refund if the cancellation request is received before the order has been shipped. Once an order is in transit, it cannot be cancelled - you may file a return claim after delivery if applicable.
If something went wrong with your order, contact us before involving your bank - it is genuinely the faster path. We review claims within 1 business day and issue approved refunds to your original payment method, usually well before a bank dispute would even be assigned a case number. A chargeback typically takes 60–90 days to resolve and freezes the amount for both of us while it’s open.
