Rude man named "Bob" won't give you his last name or tell you what he wants or what he's selling.  Gets very defensive when I say my husband's not available.  Claims to be from Federal Security which is not even listed in the yellow pages but is located in NW Oklahoma City in Atrium Towers.  Hung up on me because I questioned everything he had to say and we're on the DO NOT CALL list.

this guy  from Federal Security called us, and asked for the wrong name when i told him the right name he hung up.
for a second i was worried that it might in fact be a federal service so i tried to call back but got only on his voice mail.
i google'd the number and found out that there is no federal security and then found the link to this page, so i assume he's just a scamer and i will inform the real FBI about him.

Just got a call from Bob, same thing...said he was from the Federal Security System....creepy.

My wife got a call from Bob asking for me by name. I went to the phone and told Bob in no uncertain terms that I was not interested. He said, 'but you don't even know what I'm offering. How do you know you're not interested." I told Bob that I knew because "if I were interested in whatever it is you have to offer, I'd have called you." I then hung up, and advise anyone else to do the same.

Received a call from this number. Answered by just listening without speaking. Caller didn't say a word and hung up. Creepy
