How do I cancel my SIR to USC?

<p>I submitted a fee waiver request for USC, and I guess it got automatically approved or something because I got my USC email and stuff. But I'm already registered to go to Berkeley and I need to cancel my SIR to USC. I called them and sent them an email last month to cancel my offer of admission, but they keep sending me letters in the mail and emails too...I don't want them to bill me or w/e in the future so how do I officially cancel my admission?</p>

<p>Call admissions and tell them you wish to withdraw and want to be removed from their enrolled student database.</p>

<p>This may be good news for a spring admit.</p>
