Can I also redeem this voucher for a Swiss Spotify account?

I bought the Spotify digital gift card for 10 months instead of 12, with the intention of giving it as a present. However, I can't find a PDF file to print out with the code to give as a present. I simply have the code loaded into my customer account. It's a shame, I'm disappointed! Do you have a solution?
