I called back and it is First National Collection trying to collect on a debt.  My attorney told me to say this:

"I am telling you not to call me again and to cease all communication with me about this claimed debt. This notification is pursuant to the Federal Fair Debt Collection Practice Act, 15U.S.C Section 1692 (c)(c), and does not admit any debt. If you call me again I will report you to the Attorney General and you will be fined."

If they call again, report them. I have found that they stop calling after this.
