I dropped off a package on Friday, Jan. 26 around 4pm, at the Naperville (60540) post office on Washington Street, that contained a flat poster. Tracking number 9400109699939643601541. It has not been recorded as received by the post office yet. My concern is that it was mistaken as an empty flattened box and discarded with other cardboard. Can someone please look around the office for it?
