In this case, the carrier company could not successfully deliver your package, This means that the carrier has attempted delivery several times but no one was home. Usually, the carrier will leave a card for you to pick up your package from your local post office or parcel warehouse, or return the next day to try one more attempt to deliver. If both times the carrier is unsuccessful then your package will return to the sender.If your package is being returned to our warehouse then once we receive your package we will issue you a refund. To process refunds for return to sender packages we wait 14 days until we receive the parcel and a further 7 days to process the refund, in total it could take up to 21 days.TIP: Many of our carriers allow the customer to add details and instructions during the transit of their parcels, this means you have full control over your parcel and you will know exactly the day of delivery, schedule it, add authority to leave and much more!
