Since they've been calling my house number for over a week I finally picked up.  Turns out they had the wrong number.  The guy identified himself as a Steve Smith (did not say what company he was with) and asked for some guy that I've never heard of.  Sadly, I think when we moved into our new house, we got an old number of someone who the creditors were/are after.  This is not the first time we've had this happen.  We'll see if they call again.  When I told him that I've never heard of the guy before, I don't think he believed me.
