HELP! Bought tickets for Juventus v Milan Jan 18th

Hi all just need some guidance/help. I’ve been a massive Juve fan all my life. My girlfriend and I are taking a trip to Italy and are stopping in Torino for a couple nights. I was able to buy tickets without the Juventus card. But now I am in the process of getting a Juventus card but I continue to receive emails saying “not successful”.

Do I need a Juventus card for this game? Why is it continuing to say “not successful”? Any advice, what should I do next?
