Thanks for the suggestions guys.

I have a nice update: checking the tap site today I discovered the option to request a full cash refund. So I called support in Denmark and in about 15min everything was sorted. Now I have to wait 30-40 days to get the money back in my credit card.

At the bottom of the page you'll find a link called "other forms of refund".

Good luck everyone!
