Green Thorn shipping issues

Has anyone ran into something like this before. I purchased a large Inkosi and the tracking they gave me for China post was showing some weird info. I contacted Green Thorn for the USPS number and this is what I am seeing now. Green Thorn told me to reach out to usps to pay the outstanding postage… they said they would reimburse me but I still thought it was odd. USPS told me that the package is essentially gone since the proper postage was never applied.

Odd situation all around. Green Thorn has not yet offered to refund or send a new one, but I’m waiting for their latest response.

Having said that if anyone has an extra large Inkosi from GT laying around I’d love to snag it from you. I was hoping to grab a second after this one came. If I happened to find several I’d just press for a reimbursement on AliExpress.
