You find it very difficult to work there because he or she always has friends visiting. They have parties in the room and sometimes borrow your things without asking you. Write a letter to the Accommodation Office at the college and ask for a new room next term. You would prefer a single room. Explain your reasons. Dear Sir or Madam, I am writing to inform you that I wish to move into a new room next term. I would prefer a single room, as I find the present sharing arrangement inconvenient. I must explain that the reason for my dissatisfaction is my roommates inconsiderate behavior. For one thing, his friends are constantly visiting him; for another, he regularly holds noisy parties. In addition, he sometimes borrows my things without asking me. In these circumstances, I find it difficult to concentrate on my studies, and I am falling behind in my assignments. I am sure you will agree that the only solution is for me to move into a room of my own, where I will be free from such distractions. Therefore, I would be grateful if you could find a single room for me, preferably not in the same building but as near to the college campus as possible. Yours sincerely, Janice Kennedy,1,Sample 2 You have received your pay for your summer holiday part-time job, but your pay is less than you were promised. Please write a letter to the manager of the unit, clearly stating what work you have done and how long your work took. While explaining your case, put forward your demand and suggestion. Dear Manager, I have received the $800 check which you pay to me as a part-time software programmer in your company during my latest summer vacation. However, I am at a loss why the amount is $ 100 less than you promised to pay me. It was contracted that a part-time software programmers weekly wage is $ 300. I signed the contract with you and consequently worked in your company for a total of 3 weeks. In the period, I went to and from work on time and to your satisfaction, I completed each task that you assigned me without any errors. Also, no blame about me was ever heard in any aspect. So my total income should be $ 900, which is $ 100 more than that I gained from you. I firmly insist on your kind explanation of the difference and making it up as soon as possible. Your early reply would be highly appreciated. Yours sincerely Janet Smith Sample 3 Dear Manager: Much to my regret, I write this to place a complaint against your bad delivery service of your company. The Samsung tape recorder model number JB/4703 that I ordered from your company on Nov. 1, arrived yesterday. The serial number of the machine is 4703 -0641. I am sorry to report that the recorder has been badly damaged. There was no unusual damage to the packing case, but when I opened it, I found that the lid of the recorder had been cracked and that the front surface of the machine had been scratched. Since there was such damage to the goods, I decided to file a complaint against the delivery service. Would you please let me know whether I should return the recorder to you for a replacement or if you have an authorized service representative here to which I should take it? I will hold on to this recorder until I hear from you.
