why are you calling me

I am repeatedly getting calls to my home phone from various bill collectors to S. Smiths of all types - Stephanie Smith, Sarah Smith, Steven Smith, etc.  No one by those names or any other SSmiths (other than me) at our home number.  I have an almost perfect credit rating, no bad debts, and in the last few months or so somehow I am getting almost daily calls.  Not from the same collectors; this is just one.
