英语作文 假设你是李华,学校组织夏令营,欢迎外国学生参加.请用英语写一封信邀请你的美国

Dear Editor,
I have joined an English summer camp recently but I am very disappointed because the organiser didn't keep their promise. I had wanted to improve my English by joining in the camp but there were 60 students in a class so we had few chances to practise our English. Besides, the lessons were easy and the topics are out of date ,which couldn't arouse students's interest in English. What's more, there was no lunch at the school so we had to walk thirty minutes to have meals at the nearest restaurant. The school had promised a variety of activities in the advertisement but they actually only organised one badminton match.
In a word, I am very disappointed and dissatisfied with the camp ,so I submit a claim for compensation here. Please help me.
Thank you.
Yours,
