[填空题]Dear Manager，
I am writing to you to complain about the service in your hotel．I had a terrible stay in room 2532 of Orange Hotel from the 16th to the 19th in March 2009 when I came to Bering on business．
Firstly，the air conditioner in my room could not operate properly．I asked your front house manager for help and she told me she would send someone to my room to check it immediately．No one came．As a result． I was very cold every time I was in the room．
Secondly，I found the bathroom was dirty and the hot water was always warm．
Thirdly，the noise at night was extremely loud and I found it difficult to sleep．
I hope you will give immediate attention to the service in your hotel．

Yours faithfully，
John Smim
