That's... Bizarre.
I know that USPS sucks sometimes, and I've had issues with them domestically, but to just not let people know where their international shipments are!?
I don't think it's that uncommon. From my experience being in the States (around a year, collectively) the postal/courier services there are pretty abysmal in comparison to what I've experienced in Europe, lol. Kinda like the quality of internet.
