Hey there @simonderboi and welcome to the community! Unfortunately, gift cards can only be redeemed in the country in which they were purchased.
I recommend reaching out directly to Spotify Support. They can be reached through their Twitter Page @SpotifyCares or through the online contact form. There's no guarantee that they can change the info on the card, but it's worth asking!
Make sure to check your inbox and junk folder for an email from Spotify.Once you get it, make sure to reply back right away, even if it says it's from a "no-reply" email.
