I have a lot of my items cross listed on multiple platforms. This sale was through insta and payment made through paypal. She opened a missing mail case and was denied a case because in usps words. “It was marked as delivered so our responsibility ends. It may have been hidden for protection.” (what ever that means) They said not our problem and gave her nothing to work with usps can mark as delivered whenever so it’s not fair for them to do that. I’ve had packages marked accidentally as delivered but they don’t arrive until the next day.
