This was in my inbox first thing this am:

A few minutes later came:
Dear Dorothy Pecson,
Your Apple ID was just used to download 明珠三国OL from the App Store on a computer or device that had not previously been associated with that Apple ID.
If you initiated this download, you can disregard this email. This email was sent as a safeguard designed to protect you against unauthorized activity.
If you did not initiate this download, we recommend that you go to iforgot.apple.com to change your password, then see Apple ID: Tips for protecting the security of your account for further assistance.
您的 Apple ID 刚刚在一台以前未与此 Apple ID 相关联的电脑或设备上从 App Store 购买了 明珠三国OL。
如果购买此内容的不是您，建议您前往 iforgot.apple.com 更改您的密码，然后参阅 Apple ID：保护帐户安全性的提示 获取更多帮助。
So I changed the credit card immediately; changed all my email passwords; called APPLE and was told to contact iTunes - who only does email and may respond "within 24 hours"!
Any other suggestions?
PS - I repeat, HELP!!
