This person just called several times in a row, speaking some foreign language after I said "Hello". The first time I said "You have the wrong number" and hung up.  They immediately called back, twice in a row, and I let it ring without answering.  The fourth time, I answered and said "You have the wrong number, please do not call again".  They immediately called back, and I let my wife answer.  She said, "Take us off your call list" and hung up.  It rang again, and my wife answered, and the guy said "Who is this?".  My wife said "This is my home.  It doesn't matter what my name is" and then she started using profanity and hung up.  That was the last call since then (five minutes ago).  It must have been some time of phone bank, because we could hear other men talking in the background during these calls.
