If the account has been deactivated, it can be reactivated - but you need to log in somehow. I'm afraid it was a really bad idea to use a temporary email address as a credential that you might need to re-use, and Evernote Support are the only folks who may be able to do anything about it. They're away for 2 days with Thanksgiving, under a lot of pressure anyway, and a Basic account gets last priority for support requests - so I suggest you get your request in as soon as possible, and use another basic account (and a real email address) in the meantime.
My Account also disappeared out of nothing. I can restore nothing, very disappointing... The notes I've made were very valuable.
