Called every day for 3 days and left no message. Unknown Name.
I called back today. He said he was from the American Veterans Support Foundation.
I asked him why there's Unknown Name and that I was filing a complaint since I didn't feel it was legitimate.
He hung up on me.

I did file a complaint with the National Do Not Call Registry.

I used *67 before dialing to block my phone number just in case it was not legitimate.

NOTE: *67 does not work with 800 numbers; the number calling from will still show up.
