this person pretend to be a relative and ask questions about my family i don't recognized his name and i started to ask him who were his parents and he ended the call

this person pretended to be a relative of my wife's and he asked personal questions about my family. I know he is not a member of our families. I then asked him who he was and who his parents were and he hung up on me as soon as I started questioning him and suspecting his motives.

This man continues to call my house number and asked if I know who he is. He states to be my relative from Mexico and wants me to guess who he is. Then he hangs up as soon as I question him.
