Mine stuck since the exact same date. US customs (ISC NEW YORK NY)
I enquired with USPS, they replied:
"Tracking is showing item is still in Customs. When Customs receive an item that item belongs to Customs until the item is released. USPS cannot take possession of the item until it clears Customs. You should contact the sender and inform them that the item is still in Customs. Please contact Customs concerning this package @ 8002221811 or 8772275511."
Has anyone actually tried to call customs? I ~hesitate~ to...
