Withdrawing from other colleges, but they wont reply back?

<p>I’m committed to Brown’17. </p>

<p>So, I’ve been emailing other colleges and universities that I am withdrawing my applications.
So far, I only have two that have not replied back to me yet. They are not responding to my emails nor my letters.
Specifically, how do I withdraw from NYU and UC Berkeley? I’ve been emailing just like how they tell me to do on their website.
But, no reply for over a month.</p>

<p>What should I do?
How did other people who have been accepted early to Brown Class’17 withdraw from the two schools? </p>

<p>Thanks in advance.</p>

<p>You’ve already done whats required.1 email or phone call completes your job. Your done.</p>

<p>congratulations. i agree with the above poster. you have done everything required of you. it is not your responsibility to follow up with them.</p>

<p>Okay. Thank you :)</p>
