iTunes Store

good morning my account is blocked iTunes invisible for what reason

If you mean that your account is disabled (as we are fellow users we won't know why ; 'iTunes invisible' ?) try resetting its password (and then logging out and back in everywhere) : If your Apple ID has been locked - Apple Support

If that doesn't fix it contact iTunes Support and see if they can/will re-enable it : https://www.apple.com/emea/support/itunes/contact.html
