The same EXACT thing just happened to me last week. I couldn’t get a hold of the vendor to find out what was going on so I went straight to escrow and messaged them that I wanted it fixed or I was requesting a refund. A day or 2 later the vendor sent me a tracking so I still don’t know wtf this is going on. My order was lingering in “partial” status and not completed but he must’ve fixed the issue on his end (or maybe added the few bucks himself?) because the order was completed.
