Student discount not working

[miexxx]

Hi! 

I tried to sign up for the student discount, and got a verification mail:

"You're verified!

We verified that you're enrolled in an accredited college or university, which means Premium for Students is but a few clicks away. Go back to Spotify to complete your purchase."

But how do I do these "few clicks"? 

If I click "get discount" on spotify.com they want my credit card information and a valid document, which I did to be verified..
