| 任务型读写 请认真阅读下列短文,并根据所读内容在文章后表格中的空格里填入最恰当的单词. 注意:每个空格只填1 个单词. Customer service refers to the way that companies behave towards their customers. It's the quality of service that determines whether the customer remains with the company. However, many a time organizations don't focus on customer relationship management, and that's what makes customers angry, which is one of the reasons why companies lose their customers. So customer service is vital and you should know how to improve it. First of all, you need to realize how important the customers are. It's they who are the boss, and it's because of them that you get your pay checks. So do take your customers seriously. Finding out the needs of the customers is another important customer service tip. You need to ask the customers the right kind of questions and think of the possible solutions which you can provide.Understand how they feel according to a particular situation, their body language, tone of voice and words. Never make assumptions and think that you know what the customers want. Making customers feel they are important is an excellent way to serve them better. Treat customers as individuals and the best way to do that is using their first name and finding ways of praising them in a sincere way. In addition, there are some other skills which will help you to serve your customers better. For example, once you finish solving the problem for the customer, before ending the call, always remember to ask if there is anything else you can do for them. End the call with a "thank you". If customers are angry, let them express their anger completely. Never interrupt or start speaking until they've finished. Once they've finished speaking, try to calm them down by apologizing. In a word, always remember that if the customers remain happy, you'll be in business.
