I replied to the original email that they sent me at 9:00 AM ET on Feb 20, 2012.
That email was sent to my Gmail email address.
When I replied, I received a confirmation email with a reference number.
24 hours passed with no reply, so I submitted a support ticket via the support page within the Dreamhost panel.
After I did that, I received a confirmation email with a reference number.
On my support page within the Dreamhost panel, I have two open support tickets listed.
The first one is 1 day 2 hours old
The second one is 2 hours 39 mins old
