Today,  this place called my mother's house.   I haven't been there for over 30 years.   They refused to identify themselves.   She hung up on them.   Told her I was glad she did.   Sounded like predators trying to scam her.  I did a search on the number and could only come up a location in AZ.

I tried calling this number from my house phone (I have my Caller ID blocked).  The first time the number wouldn't go through.  Tried again.   There was a long pause,  but then the number rang.   A man answered the phone yelling "hello?, hello?"  Not a business,  so I hung up.
