While the end will be a mess no matter what, I think it would help if you posted a few more details about exactly what happened.. especially because "premium economy" is an oft-misused term by the common traveller and does not often mean what "Premium Economy" does as a technical term.

You initially purchased a Basic Economy ticket from United, for travel on some mix of Star Alliance airlines.

- What was your original routing, and what were the operating carriers? Lufthansa does not fly from the USA to Poland (nonstop), and there is no Premium Economy cabin on LH flights within Europe.
- Who did you pay $120 for the ticket "upgrade"? When did you do it? How did you do it?
- If you know, what were the fare classes on the receipt for each segment after you paid for "an upgrade"?
