We apologize for the inconvenience. Upon further review we have been able to verify your account. The mail service used for your credit card to provide a US address for a China based account caused a fraud flag in our system.
Preventing fraud is a priority but unfortunately, sometimes accounts that are not fraudulent can be flagged in rare cases. We understand that this can be a major inconvenience and to compensate you for your trouble we have issued a $20 credit to your account. Your account has also been unlocked and is again fully functional.
We appreciate your patience with this matter and if we can be of any further assistance, please let us know.
