Are you for real??
Even if what you say is 100% what happened (doubt it), there is absolutely nothing you can do. Put the possibility out of your mind.
If you are on the wait list, try like hell to get off by calling/writing letters of intent, etc, but DO NOT MENTION YOUR SUSPICIONS TO THE ADMISSIONS OFFICE OR ELSE YOU WILL LOOK LIKE A PARANOID CRAZY PERSON. Because that's what you look like here.
