Suppose you have found something wrong with the mobile phone that you bought from a flagship store last week. Write a letter to the customer service center to：
1) make a complaint, and
2) give your suggestion.
You should write about 100 words on ANSWER SHEET.
Do not sign your name at the end of the letter. Use “Zhang Wei” instead.
Do not write the address. (10 points)
To Whom It May Concern,
As one of the regular customers of your flagship store, I really like your products. Sadly, I found the mobile phone I bought last week was of poor quality, so I am writing this letter to express my complaint and give you a suggestion.
There is a problem that the battery needs recharging after a mere 2 hours of use. As a result, I need to carry my charger with me when I go out for a day. Personally, it would be better if you could prolong the battery life through scientific and technological innovation.
I really hope you can settle the matter as soon as possible. And I would like to extend my greatest appreciation if you are so kind as to take my suggestion into consideration.
