When you say "email" did you use the email contact form on the PM home page? If so, that has been unreliable. The best way to obtain help is to private message like I mentioned. If you've done that, then it's best to be patient, as there is currently a longer than normal response time (2-3 days) due to the heavy volume of help requests from the Freedom-targeted promo.
I recommend you turn on e-mail notifications for receipt of private messages in your community account. To do this, go to Settings -> Preferences -> Private Messenger. Tick the checkbox for "Receive email notifications for new private messages" and click save after making the change. That way, you'll quickly see any reply from mods without having to constantly check your community inbox.
