HELP : "please contact itunes support to complete this transaction"?
Hello everybody. I'm from Vietnam. Recently, i've used my itunes account to purchased apps, songs, games, etc. But when i input my visa card number and code, there is a error shown up "please contact itunes support to complete this transaction". I can't purchase itune gift card or any apps in US store. I don't know how to fix this problem. So anyone know how to contact apple support by email( not phone 'cause i'm in Vietnam) or how to fix this problem directly please help me. Thanks in advance.
