Dear Sir,
My name is Wu Peng.l am one of your customers.I venture to write you a letter about my refrigerator bought from your shop 2 weeks ago.The focus of the complaint is the quality of the refrigerator.For one thing,I found it didn't refrigerate well.For another,it made such loud noise that I couldn't fall asleep at night when it is working.Honestly speaking,I have observed it for a few days.And there are still something wrong with it.
All in all,there is still much room for improvement.I do hope you can send an engineer to check it or exchange it for another refrigerator of good quality.
Thank you for your time and kind consideration.
Sincerely yours,
Wu Peng

亲爱的先生:
我叫吴鹏，是您的客户之一。我冒昧地给您写这封信，是关于两周前从您的商店买的冰箱。投诉的焦点是冰箱的质量，一是，我发现它制冷效果并不好。另一个，它工作时会产生很大的噪声，这令我晚上无法入眠。老实说，我观察了好几天了，但还是有一些问题。
这仍有很大的改进空间。 我希望您能派工程师来帮我看看它或更换另一个质量好的冰箱。
谢谢您宝贵的时间和善意的考虑。
真诚的，
吴鹏
