As I understand it, the OP flew on the "non-refundable" fare, so therefore "consumed" the seat and bag payments on the return flight. As such, no refund would be due, as these purchases were used (on the return flight - (s)he was a no-show for the outbound).

As I understand it, the €500 was for a return flight. The OP knew (s)he was going to miss the outbound of the original booking, and therefore bought a new, second, fully-refundable return ticket.
