please help me to correct my writing, thank you in advance.

Dear Professor Wang,

My name is Guangyu.  I was enrolled in a four-month, part-time advanced English training course at New Century College, twice a week in the evening from last month to August.

I am writing to inform you that regrettably there has been an unexpected change in my work schedule. I am a full-time civil engineer with the Beijing Damei Real Estate Company. Yesterday the director of my department informed me that the company has decided to send me to our Shanghai branch for three months to work on a new project. Therefore, I will not be able to attend the rest of the classes. It is a great pity and I am really very sorry about having to leave the course.

I wonder if you could help me defer my course to next semester so that I can continue my studies when I return from Shanghai. Otherwise, if there is no option other than to quit, would you be kind enough to help me get part of my tuition fee refunded.

Thank you. I look forward to hearing from you.

Yours sincerely,
Guangyu

Dear Professor Wang,

My name is Guangyu and I was enrolled in a four-month advanced English training in New Century College (用的语法有一点错误）

(选项 1: "...I was enrolled in a four-month long advanced English training course in New Century College") 

(选项 2: "...I was enrolled in four months of advanced English training in New Century College")

, which is a part-time evening course, twice a week from last month to August.

I am writing to inform you that there is an unexpected change in my work. I am a full-time civil engineer working for Beijing Damei Real Estate Company. Yesterday the director of my department informed me that the company decides decided (注意时态) to send me to the Shanghai branch for a new project for three month months. Therefore, I would not be available to attend all the rest remaining courses. It is a pity and quite a loss to me to quit the study.

I wonder if you could help me to postpone my course to the next semester for me to continue my study when I come back from Shanghai. Otherwise if I must quit, could you kindly to help me to refund part of my tuition fee. (用"kindly" 在美式英语里有一点怪怪的。"please" 相对好一点)

Thank you and look forward to hearing from you.
