【答案解析】Dear Sir/Madam,
I am writing to you to express my complaint about the ipad I bought from your online store the other day.
At first, I was quite pleased with my new learning device. It worked just fine. Unfortunately, after playing some games on it, the screen freezes every time when I try to get access to the "Dictionary" application. I reset the device several times but now the problem still exists.
Therefore, I suggest a free replacement of what I have. Also to avoid similar complaints, your company should run stricter quality tests on products. Your prompt attention would be highly appreciated. I look for ward to a satisfactory feedback.
