Why won't my facebook account reactivate? I don't even get the email for reactivation.

So I deactivated my facebook account and cannot reactivate it. I had my facebook account throughout my undergrad (4 years) and now in med school.....I haven't been able to reactivate the account. I know I changed my primary network to my med school from my undergrad, but haven't received any email reactivation notification. How do I get in contact with facebook employees?
