Who called from 4164397445

Asked for my wife and when i asked what it was concerning they refused to tell me and hung up on me.  gotta be a scam said it was a courtesy call.

Asked for Mr. or Mrs. _________, when we said, go ahead, he said, "Oh, I don't answer the phone that way at home, I'll call back later,"  and hung up.

i answered the phone and said "hello hello" and waited and they hung up.

this # called then hung up.....?

This # 416-439-7445 called today for my mother who passed away in 2005. When I call this # back there is no answer there. Who are these people????
