Never seen this happen!! Help!

Hi guys. Ive been selling on PM since 2016 but this is my first time having this happen. I sent a jacket to a buyer, and I usually message the buyer when I ship to let them know it is in the mailbox. I did that, and no response (which is okay). A few days later I check the order status and I get this message (see pic) so I message the buyer again letting them know to reschedule or pick up from the USPS and no response. Its been days and nothing has happened. Did i get scammed ? Has anyone else dealt with this before?
