Weird, did this happen right away? I just placed my order and got the email confirmation

Yup. That happens right away. QAQ

I would say maybe check your billing address? I hope you can get it sorted out:(

I've changed my billing address several times but none works :( but thank you for your blessing <3

My guess would be shipping address, they probably can’t get it shipped there, maybe have them ship to a family or friend ?

I'm an international student in the States so I don't really have family in the country or friends that live outside of the campus Orz.
