Just a piece of information as to how Sendle works for those that don't know. Courier gets scheduled to pick up packages from a location, usually a couple of days in advance. Courier picks up then off to recipient. That, along with it being this close to Christmas, may take a little bit longer.
Sorry, but some impatience from people who have been burned by PC makes people paranoid about another business. Bombarding them with messages won't help get responses any quicker.
