one option would be that you use Contact Customer Care = http://helpx.adobe.com/contact.html, by clicking through the headlines.
If none of the conditions is fulfilled, and if "open" please use chat, I had the best experiences. I quote from Preran: The chat button is activated as soon as there is an agent available to help.
This contact link is "brandnew", please give it a try: What are my contact options?
On the other hand you can have a look there: "Telephone numbers of customer service and technical support Adobe worldwide" >>>
