That’s sadly their modus operandi (and kind of the AliExpress shipping model for some big shippments)
I think they don’t have much stock. So they send once they’ve produced. In the meantime they provide random numbers. If you spam them enough they’ll send you a viable tracking number. (Which at that point means they have paid for shipping and now have an actual tracking number and the shipping sticker).
And the funniest part is to come. Usually ups take care of the package once it as reached the destination continent. (So once out of the cargo ship, or plane). In the meantime you’ve got an uncertain time where your package could be traveling already, or not at all.
You’ll probably get your stuff at some point. Keep and eye out and bugging them from time to time, to be able to fill a claim with AliExpress if this get out of hand. And maybe speed things up a little
