Apple ID Support (2) 

Apple Support by e-mail or chat    Work through the screens to get a chat option.    

Apple Support using Twitter

Or fill out and submit this form.          The form is for iTunes, but it will get passed to the ID Support section.  

I seriously doubt that they told you to contact Apple Support Communities.

If they did, they certainly would have instructed you to provide far more details then you have so far. With the information provide there is no way we can help you.
