A few words from Tech Support:
"When you call a tech's direct line, press 5 to skip the bilingual greeting that says he's out of town for a week, record your message and wait exactly 24 hours before you send an email straight to the director because no one ever returned your call. After all, you're entitled to common courtesy."
