Female caller called at 4:18 p.m. (I was not home from work and my 12 year old answered.) She asked for my oldest son,caller hung up.  At 4:20 p.m. the same caller called again, this time asking for the parents of Melissa (ME, the parent), to which my son responded that I was in the shower.  I called the number back and the female on the other end said that without a name, she couldn't tell me who called.  I asked who WEST was, and she said a customer service agency.  I asked her what that was, and she said a larger customer service agency that is over alot of smaller agencies.  I asked her what that meant, and she offered no other explanation.
