Dear Sir or Madam,

As a customer who has purchased an electronic dictionary from your store. I feel quiet disappointed with the quality of the dictionary. The purpose of writing this letter is to make a complaint.

First and foremost, there is something wrong with the screen of the dictionary, which prevented. me from preparing well for the upcoming exam.Morever, I am dissatisfied with your after-sale service. It was you who promised 24-hour online support, however, no one answered when I called twice. Therefore, you are supposed to provide me with a new one or refund my money.

I kindly request you handle it as soon as possible.

Yours sincerely,
Li Ming
