My Question or Issue
I had spotify premium for a year (started in January 2019) until I forgot to renew my membership a few months ago. I've just realized I forgot it when I checked by bank account. When I tried to renew it, it failed (check the attachment).
P.S. I also got to say that when I first applied to premium, I was a student in "Karadeniz Teknik Üniversitesi" but I had a transfer to "Akdeniz Üniversitesi" this year. Maybe this information can also be helpful to solve the problem.
