Item sitting in "Pre-Shipment" for over 2 weeks?

[sirarmysuit]

I bought an item on July 2nd from the US, and on July 6th I was notified by email that the item was "Being shipped to the global shipping centre." And that's it. I have had nothing since then, no shipping updates at all, and I have messaged the seller twice about it, to no reply. 
Whenever I look up these global and domestic tracking numbers I was provided, UPAAC000000055184775 and 9405509699938575894864, it only says "Shipping Label Created, Not Yet in System" and "In Pre-Shipment"

The latest delivery date estimated is the 25th. If the 25th passes and I do not receive my package by then, what should I do? 

I just want to know what my best course of action would be. Or if you guys think it will still come. Who should I phone? Am I worrying about nothing? Did the carrier forget to scan it somehow initially and it'll just show up?

You may want to sign up for shipment alerts at GSP/USPS and then you could have a better idea once things start to progress or if they aren't, what so ever, then you could follow up using the contact seller button attached to the transaction.

I've contacted the seller twice, and he has never replied to me unfortunately. But I'll look into that.

Once the purchase is delivered to the GSP plant, the seller has no more responsiblity and no more ability to help than we Boardies do. But he should at least have made reassuring noises.
