Lufthansa sucks

Hi
I have tried to find the prizes on having one surfboard a mini-mal 7`10" with me from bali and home to norway. And i found this: fligths in europe cost : 50 euro, but on my flight ( from Frankfurt to Oslo) Lufthansa say that they haven`t got room for a surf board. :(
the prizes I got from singaporeair from bali to frankfurt was around 5- 10 euro.
anyone know how to get a surfboard from frankfurt to oslo???
