听力原文： Most reliable companies pay close attention to customers' mails, particularly from dissatisfied customers. But writing letters to a company is one thing; getting the company to do what you want is another. And it requires a certain amount of know-how to persuade a manufacturer to repair your broken toaster or to make an adjustment on your mishandled airplane reservation.

First, you must observe certain principles. The most important is that you must deal with a reliable company. If you buy something from a fly-by-night retailer, you have to accept the fact that you have thrown away your money.

Second, if the product carries a warranty, be sure that you understand its terms. The warranty is an insurance policy, and the customer pays for that insurance when he pays for the product. If a product becomes defective a few weeks after the warranty has run out, some companies may make the adjustment, only for the sake of good will.

Third, let the company know in no uncertain terms that you are disgusted with its product or service, more often than not, customers who write in anger sometimes forget to include important information that the company needs in order to correct the situation. If that information is lacking, all the anger in the letter will get you nowhere. On the other hand, a simple, calm, factual and reasoned letter can usually help you to achieve the desired end.
