The letter of complaint

From: 663, Pham Hung Street, Soc Trang, Vietnam
To: The Director
English for Today Centre
731 Phu Loi Street, Soc Trang, Vietnam

Dear Sir,
I am writing to complain about the poor quality of the service at your centre. Everything seems to be worse than what you say in the advertisement.
First, You say all the teachers at the centre are only the native, but in fact there are so many Vietnamese teachers in the centre. Second, most of the class are more than 30 students, but the advertisement said that there are no more than 20 students in the class. And in the advertisement, you say books and tape cassettes are free, but we had to pay for them. And the thing that annoys us so much is most of the rooms are not air-conditioned, it uses fan instead.
Finally, the class time is not the same as that in the advertisement: the class begins too late, but it finishes early

To resolve the problem, I require you to give me the refund. Enclosed is a copy of the receipt
I look forward to hearing from you and to getting a quick resolution of problem. Please contact me at the above address or by phone at (09) 99 999 999

Yours faithfully.

Nguyen Huynh Phuc Loi
