Try chatting with them in Swedish, it's fun.
First they told me it was due to no ticketing agreement, so I showed her their website that says they do have one.
Then she said I must have booked a different airline, and I said I didn't.
Then she said it was due to a price mistake, so I told her that the cancellation email was a lie.
Either way, Swedish is a cool language to copy/paste from Google Translate. Very Viking'ish
