<p>I got accepted to another school via ED2, and I got accepted here during EA, and I’ve sent them an email more than a week ago about trying to withdraw.</p>
<p>The website link they have to filling out a form doesn’t work when I put in my birthday, it says “INVALID DOB” for some reason even though it’s perfectly valid.</p>
<p>Try snail mail. Just write a short (can be as short as one-line) letter withdrawing your app. Thank them for their consideration (second line). Keep a copy. Done.</p>
