Claimed to be Angela Davis from CPG Processing Services.  Stated company has been trying to serve a complaint on a relative but no response had been received.  Wanted to know the whereabouts of relative and when I stated relative was not living here, the caller proceeded to say she did not believe me and she was sending the sheriff to the residence.  She then hung up on me and called another phone in our household.  She told that person the same story but would not elaborate on the issue, only calling regarding serving a complaint on the relative and stated she could not give details.  I called back to verify the phone number and company name given to us and it was the same person who called prior.  Something fishy here.....?  Any others receiving the same type of calls?
