Orders go to the address entered at checkout. Delivery options and any charge are calculated there from that address and these items, and are shown before payment.
When an order ships you get a confirmation, with tracking wherever the carrier supplies it. After dispatch, the estimate on the tracking page is the carrier's, not ours.
Damage in transit, or a parcel that never arrives: email support@qankyaq.com with the order number and we will file the carrier claim.
Duties and import charges, where they apply, are set by the destination's customs authority.
