we recently started to get calls from this #.  today I picked up the phone.  at first there was nothing there, then a recorded message to say
someone would be with me shortly. i waited.  then a lady asked for my adult
son with first & last name.  I asked who was calling.  they would not answer that question.  only wanted to speak with my son.  I told them he
was not home and they said they'd call back.  before i could get out--put
us on you're No Call List-- they had hung up.  Tonight they keep calling.
I answered once.  There was no one there. and No recorded message.  Who
could they be?  My son is a college student, no unpaid bills, etc.
