I phoned the CBS Moonlight demo phone line... ( 818 ) 655-1779.... to see if the box had been emptied yet this morning. As of 8:15 AM Central Time, it was still full. Next, I called Audience Services ( 212 ) 975-4545. The operator I spoke to was friendly. She said "we have a California number set up for Moonlight calls" and gave me the demo line info. Her advice was to wait until after 9:00 AM Pacific to give them time to clear the voicemail messages. I say.... just keep calling until you get through. This is very important! They will stop logging calls at 6:00 PM Eastern today!
UPDATE ~ as of 9:30 AM Central, the demo line mailbox has been cleared. Calls are going through now!
