The title is a little misleading, since many of the tips won't cut the wait to anything close to ten seconds, there are a lot of good ideas.
And some not-so-good ones. For example, "don't pay your bill." While that will eventually generate a call from the company, it's going to take a couple months and you probably won't get much in the way of customer service (unless you consider, "Pay up, deadbeat, or we'll send Luigi after you" the height of friendly corporate interaction).
Personally, I would have also put the list of "Cool Services" at the top of the list instead of the bottom, but that's just me.
