He ask me same question in the morning before 9:00am and I toll him  person that who you looking for is not here.  
thank you for your info.

Got a call from them this morning. Did not answer, but then called to see who answered. Some man (Walter) said he was Nat'l Enterprise and was trying to verify my ssn. I told him I dont give my ssn to someone who just calls and hung up. I waited 5 min., called back, was answered with "National Enterprise, this is Walter". I proceeded to say "I don't know who the hell you are, but don't call this number again as I am reporting you". He just hung up.

The company name does not show up on caller I.D.  I do not answer calls that come into my home un-identified.  I did however find out that this number belongs to National Enterprise Systems (NES).  They are a debt collector.  If you google their name, you will find that they have many complaints on them for harrassment.
