Anyone know who this is???  They call my house over and over, but never say anything...

the number comes with "unknown caller."  I don't answer calls from any number I don't know.

Received a call from this number, answered as it was a local number and due to my job I receive 20 calls a day from numbers I don't know. It was someone from a collection company in Minnesota? looking for someone I had never heard of.  I live in Kentucky, how are they calling from Minnesota with a local Kentucky number? I told this man I had never heard of the person he was trying to reach and to remove my number. We will see if it works...I doubt it very much.
