How to decline admission after enrolling

<p>Hello,</p>

<p>I enrolled at Michigan in about mid to late April; however, I received a letter of admission from a school which I was waitlisted at about a week ago. I visited that school earlier this week and decided today that I want to attend there instead. How do I go about telling Michigan that I won't be attending even though I put down a deposit?</p>

<p>P.S. - I sent an email to some address, but I'm not sure if it's the correct one. I looked on the website and called the office of undergrad admissions, and they said to us the search button. However, I still can't find it. Any help is appreciated.</p>

<p>Call the admissions office. Good luck at Rice.</p>
