Royal Mail's tracking status indicates that your item has been delivered, but you still can't find it, this could be due to a scanner error. In such a case, we recommend waiting for one day before taking action, as the item may still turn up.
If the item hasn't arrived after a day, please contact the sender. The sender can then get in touch with Royal Mail if the delivery destination is within the UK.
If the item was supposed to be delivered internationally, the sender should contact the postal office of the destination country.
