Admitted then Declined enrolment

I was invited to attend the induction ceremony at Milpark business school. I wrote entrance exam and then they said I will get an invite to the induction ceremony if I qualify for enrolment. A few days later they say I was declined to study. I asked for clarity on this matter as they are contradicting themselves. An institution facilitating MBA studies for senior executives is meant to conduct itself in a professional manner. I believe every institution has rigorous processes to determine who makes the cut and who does not. Therefore there is no way one can make a mistake of admitting someone then later declining.<br> Till today they haven't given a reason of their unbecoming act. They do not show any signs of good customer or client care. I'm disappointed with such an act from a professional institution of higher learning. If they are administering an MBA course then it is worrying to me. If I cannot trust you to treat me right, how can I trust you to teach me right.
