Dear Sir or Madam,
My name is Li Hua, an exchange student from China. I’m writing to report the quality of the mobile phone which I bought from your store.
It unexpectedly went wrong a few days after I bought it. The screen turned out to be black while I was taking photos. I tried to restart it according to the instructions, but it still failed to work. Therefore, I’m sure there is something wrong with the phone. I am hoping that you direct me to a store where I may get it repaired or change it for a new one within the next 3 days. Since your store has gained a good reputation for customer satisfaction, I am confident you will process my problem at your earlier convenience.
Looking forward to your early reply.
Yours Sincerely,
Li Hua

尊敬的先生或女士，
我的名字是李华，一个来自中国的交换生。我写信是想报告我从你们店里买来的手机的质量。
我买了几天后，它竟然出了差错。我拍照片时屏幕变成了黑色。我试图按照指示重新启动它，但它仍然无法工作。因此，我肯定电话有问题。我希望你能引导我到商店，我可能会得到修理或换新的一个在未来3天内。由于贵店为顾客满意赢得了良好的声誉，我相信你会在方便的时候处理我的问题。
希望早日得到你的答复。
谨上,
李华
