Don't give up yet. Mayb you would like to give this link a try: https://wis.ntu.edu.sg/webexe/owa/pgr$adm_acceptform.main
I've read through some other posts and some applicants were able to login even though their status were "shortlisted" with no official offers.
p.s. I can't login... but still, give it a try
