Ok sounds like from the replies this is an economy booking yet I selected premium economy/world traveller plus before that page so can some one explain who one would book a Prem Econ flight on this route and what I have done wrong to end up with economy ticket?

Its obviously clear to others this is economy so some help on how to book correctly would be appreciated as sounds like needs cancelling and rebooking onto correct fare but I’m not clear how to do this?
