Hi! I am a student who receive the admission and TA letter from George Mason University. The TA offer letter is
" If you have any questions, please contact the Director of the PhD program, Prof. Sanjeev Setia at csphd@gmu.edu.
Please indicate your acceptance of this appointment by sending an email message to csphd@gmu.edu as soon as possible. "
So I sent an email to csphd@gmu.edu to ask about the deadline of making my decision.
But today I receive an letter which wrote
"on your acceptance to the PhD program of the George Mason University Computer Science department "
But I don't accept the offer. So what should I Do?
