I dropped off 4 packages at my post office last Sunday and three of the packages were delivered yesterday, but one of the packages still does not show any update. It doesn't even show that the package was accepted or processed. This package was only going from Southern Calif to Northern Calif, so it should have been delivered by Wed at the latest. BTW the other three packages went all the way to the East Coast. I contacted the Supervisor at my Post Office and she told me that sometimes packages don't get scanned or get lost and that I cannot open a case until it has been 7 days. I have not contacted the buyer yet, but wanted to know if I should contact her now or wait until tomorrow?
