I just private message CS_Agent using the envelope icon on the top right of the page. They'll answer you with instructions on how to verify it's you, through your email and then you'll be able to message directly with them.
I wish they would send a notification via text to our phones. Because I don't sit around on this website waiting for the little envelope to light up with a response. I guess that's too technologically advanced for public mobile [shakes head].
