Calls my home phone and my cell phone!

Called several times, no name was given

Call daily looking for a party that does not and has never lived at this number. Told several times to stop harrassing my household. Phone now rings and upon pickup call disconnects. I have called back the number twice and spoken with various rude individuals who claim to not understand my request.

Did these people initially call under the guise of looking for a reference?

Got a call looking for my niece and took a message. An hour or so later I get a call from my nephew(no relationship to my niece) from Utah at my sister's house looking for my niece. I called 866-613-2091 back to try to figure out what the call was all about. He than returned my call on my cell accusing me that I was someone else?  Who is this person? Calling around harrassing people?? Does anybody know??
