Help - Problems with closed e-mail address linked to the account

[BeppePA]

Hello
I've just subscribed a Premium account using my Facebook infos.
Everything seemed gone right but, when I went to my account overview page, I can see an old e-mail address of mine I had years ago and closed by now, instead of the right e-mail addresses linked to my Facebook account.
Maybe - but I really don't remember - that I had made a trial account in the past - years ago - and my PC memorized those old infos, putting them in the account overview.
Anyway, now I would refresh that address, also because e-mails are the one ways to create passwords in the smartphone app. 😞
Can anyone help me?

Thanks
PS: I obviously explained everything in Spotify support page, but the system responded the response will be sent at my account e-mail (closed) address (!).
