Customer Support representative Araxom has written up a response to just that particular situation over on Reddit. If you cannot access your account, or log into Battle.net, there is a support page that will still allow you to live chat with customer service, set up a callback, or even submit a ticket, all without having to log in. Although callbacks and live chat may not be available every hour of every day, you can still submit a ticket with this method and get a response in a reasonable amount of time. And remember -- if you're worried about account security, picking up an Authenticator is always an excellent idea.
