Hey @KaMoze, thanks for reaching out to the Community!
In order to redeem a Spotify gift card, the country where the gift card was purchased must match the country registered on your Spotify account.
In your case, your Spotify gift card was purchased in the UK, but your account is created in Poland - which explains why you're unable to use the gift card.
For this particular case, it's best to inform the person who sent you the gift card and explain to them that the country where it was purchased must match the country registered on your Spotify account.
There is some more information about gift cards here.
I hope this helps!
