Reaching a Live Customer Service Rep

I'm very frustrated when I call a customer service representative and instead reach a voice response unit asking me to "Press 1 for Sales, Press 2 for Support, ...". Fortunately, the Wall Street Journal has discovered some shortcuts to reach a live person (subscription may be required). I've pasted them here:
