My wife ordered something for my daughter on Black Friday for Christmas. It showed shipped and went back and forth all around GA. Finally stopped somewhere and she contacted the company that she bought from and they reshipped the order.
Ironically, both packages arrived the same day.
I'm friends with 3 postmasters and another guy who is very high up the food chain at the USPS and they all blame the problems on their inability to hire and FIRE employees. Either the employees are temporary with no experience and don't care or they are long time employees that cannot be touched
