单项选择题

Complaining(抱怨)about faulty goods or bad service is never easy. Most people dislike making a fuss(大惊小怪). But if something you have bought is faulty or does not do what is instructed for it, you are not asking for a favor to get it put right. It is the shopkeeper's responsibility(负责) to take the complaint seriously and to replace or repair a faulty article or put right poor service, because he is the person with whom you have entered into an agreement. The manufacturer may have a part to play but that comes later.
Complaints should be made to a responsible person. Go back to the shop where you bought the goods, taking with you any receipt(发票)you may have. Ask to see the buyer in a large store. In a small store the assistant may also be the owner or you can complain directly. In a chain store ask to see the manager. If you telephone, ask the name of the person who handles your enquiry, otherwise you may never find out who dealt with the complaint later.
Even the bravest person finds it difficult to stand up in group of people to complain, so if you do not want to do it in person, write a letter. Stick to the facts and keep a copy of what you write. At this stage you should give any receipt numbers, but you should not need to give receipts or other papers to prove you bought the article. If you are not satisfied with the answer you get, or if you do not get a reply, write to the managing director of the firm, shop, or organization. Be sure to keep copies of your own letters and any you receive.
