I did that link you refer to me (manually and using camera). But still nothing happens, always prompted "not properly activated" or "invalid code". And i did follow the instructions how to send an issue/problems/case regarding itunes card code query.
My apology dude.
I did change country/region, itunes store country, apple id, but still prompting FAILURE "The Gift Certificate or Prepaid Card you entered has not been properly activated." Does it mean it needs to activate by Apple Inc. before i can use it? If that's the case, everytime i buy an itunes card, i need to go Apple Support? Is that so?
Please help me dude regarding this matter, i know you're well knowledgeable about apple systems.
Thanks in advance.
