See if Apple can assist you via chat.  Apple is picky when it comes to getting a chat to take place about Apple IDs. So, rather than selecting for support with Apple ID, use the iPhone link, to get through to an Apple Rep via chat.

To Chat:

1. Go To: getsupport.apple.com
2. Select: Get Support
3. Select: an item, until you get an option to chat.
