This is obviously a collector calling for my 42 yr. old stepson who hasn't lived with us for 19 years now.  The caller's name is Christopher Adams (he said).  We do not know the whereabouts of our son, nor where he works or if he works.  We don't know where he lives and don't know his phone number or if he has a phone.  We pay our bills on time and have an excellent credit ratingand good folks.  This caller is harassing us weekly, is very rude, and called me a liar.  Please help us if you can.  We are innocent people being harrassed  for something we didn't haave anything to do with.  Should we call the Better Business Bureau?
