Dear manager,
I am writing to tell you that（此前为开头）one incident happened some days before . Last week I bought a TV set from your store . But when I returned home . I found that （把that 删去）it has a number(把a number改为some) kinds of quality problems like sound and colors distorted . Therefore , I took it back to store to ask for change . When I talked to the shopkeeper , however , I was treated very badly . And I was told that he won’t （把won’t 改为couldn't）solve this problem .
I think , never will a company （把never will移至company 后,并把never will删除）develop well with badly service . The service industry must improve their service quality !
Hope to get a solution !
Yours sincerely ,
Wang Ming能说说为什么吗。。。- -把that 删去，因为这句话不是定语从句；把a number改为some，因为没有a number kinds of这个用法；把won’t 改为couldn't，因为这篇文章为过去式；把never will移至company 后，并把never will删除，因为这句话的语序不对。
