关于退货的英语阅读理解

㈠ 以“假设你是李华，上月在某商店买一部数码相机，出现问题，你要求更换或退货”的事情的英语作文怎么写

dear manager，
as a customer，i have some suggestions for your sale。
last month，i bought a digital camera from your store，but after i check it by myself at home，unfortunately，i found that there is something wrong，firstly，the photos taken by it
is not very clearly。then i ran to the salesshop for mending，but they refused me。so，i had to ask an expert to testify it，later on，they told me the quality of the quality of the camera is below-average，so i had to write this letter to you and ask you for help，please respond me as soon as possible ，thank you！
