投訴信英語作文模板如下：
Dear Sir or Madam,I am writing to complain about the accommodation of the University.
There are some problems in living conditions, which are very unsatisfactory.
First of all, I think it's too early to turn off the lights at 10 every night.
Secondly, hot water supply is only available for a certain period of time, which is very inconvenient to my daily life.
Third, the dormitory has no internet access.
So when I need to do research for my study project, I have to go to the library.
These problems have brought trouble to my study and life.
Therefore, I have some suggestions: turn on the light for another hour, provide 24-hour hot water supply, and install Internet access in the dormitory.
I sincerely hope you will consider my suggestion and look forward to your reply.
Yours.
xxx.
尊敬的先生或女士：
我寫信是為了投訴大學的住宿情況。
生活條件有些問題，很不令人滿意。
首先，我覺得現在每晚10點關燈還為時過早。
其次，熱水供應只有壹段時間，這對我的日常生活很不方便。
第三，宿舍沒有互聯網接入。
所以當我需要為我的研究項目做研究的時候，我必須去圖書館。
這些問題給我的學習和生活帶來了麻煩。
因此，我有壹些建議：再開燈壹小時，提供24小時熱水供應，在宿舍安裝互聯網接入。
我真誠地希望妳能考慮我的建議並期待妳的答復。
謹上/敬啟。
xxx。
