How long does it take for Facebook to delete alternate accounts?

[Beck]

Hello,

I have two alternate accounts on Facebook. They are from a while ago so I don't know the password or the email address that goes with them. I have deleted those email addresses. I am NOT a hacker; I was pretty young (like 10 or so) so I did stupid things like making alternate accounts. I've had the one I have now for two years and I reported those two accounts as "old accounts".

About how much time will it take for Facebook to get the message and remove my two old accounts? If they generally don't respond, how should I take it from here?

Cheers...
EDIT: I could normally verify my other accounts by answering the security questions but FB won't give me those for some reason. :/
