Showed up on my caller id.

who is this

They called several times asking for someone that does not live here and has never lived here. They said they would take my number off the list but so far that hasn't happened. The person they were calling about was an acquaintance years ago and could have used my name / number as a reference but we are talking 16+ years ago.  It could have just been coincidence that they called me about someone that has the same name but if they continue to call I will be reporting them to the FCC etc.

Yes there's something that can be done - report the phone number to your local Attorney General's Office.  Every state has one.

Also report them to your local Attorney General's Office.   Every state has one!!!
