Invalid college login address, won't let me reactivate, no response yet :(

I tried reactivating my account, but the reactivation email was sent to my login college email address, which is now invalid because I graduated. I emailed Facebook for this specific problem, and they said they would get back to me. It's been 4 days, and several more emails, but no response. I would hate to lose my account because most of my college experience and memories is documented on my account. Any advice? Do I just wait and email some more, or is there anything else I can do?
