Customer call centers tend to do one thing efficiently: frustrate complaining customers. Beat them at their own game with these tips from “Gotcha Capitalism” by Bob Sullivan (Ballantine Books. $14.95):

Start by checking the Web site gethuman.com for the secret code that will get you to a live rep more quickly. Call during regular business hours, when the best employees are manning the phones. And consider pressing the number for Spanish, as you’re likely to get a bilingual operator faster than you would by waiting for an English-only agent. Or call the sales office instead. Once you get through, jot down the rep’s name or operator number, and then state your case simply. Ask if he or she has the authority to solve the problem for you. If not, ask to be switched to a supervisor who does. Take that, “hold” music!
