I booked a PFLEX ticket, and I'm confused. The online agency said in their confirmation that "first-class" tix, which is obviously rubbish in AY's case, but I wonder if it's the front or the back of the bus

I was secretly hoping that "first" would mean in fact "biz" but looking at the baggage allotment (20kg) I fear it's a humbly Y class ticket. How is the points earning for this fare?
(and should/could I raise hell at the travel agent?)
