The next step is:

Hi,

We've received your request for information about your personal data, but since there's no Facebook account associated with the email address from which you're writing, you'll need to send us a response directly from the email address that's listed on the account you'd like information about. ...

That is stupid.

I no longer have a Facebook account or even the email account that the Facebook account was tied to.

They still have data on me though.

Maybe this requirement is necessary so that people do not request info about other people.
