<time you applied> I applied to <school name> for admission in the <semester> semester. Subsequently, I was turned down for admission because, according to the letter I received, <reason for denial>. After further examination, I believe I was instead denied admission on the basis of <your reason>.
I would like to speak with someone in Admissions about this decision. I feel it has been made unfairly, and that with further consideration, you will see that I would be an excellent addition to the <school name> student body. Please have a representative from the department contact me as soon as possible.
