A is a First Class fare. You were booked in "Polaris First," which is distinct from "Polaris." You have a MOLA (Mistaken or Lying Agent), again. Sadly, that's not particularly uncommon, especially if you don't have status and are getting the regular agents.
I'd continue to call, and I'd be armed with a specific replacement flight or flights. "I booked First Class on a three-class plane, and it was swapped to a two-class plane. Could you please put me onto UA123, departing at 4:56 PM, which has First Class availability on the website?"
