Caller ID was  CHIL CANC FD AM  When I answered she ask for my wife by name and said we were very hard to contact !!  I said just a minute and got the BBB "Wise Giving Guide" off the shelf.  It is a 53 page document.  They are listed on page 19 and have a RED ( ! ) in the Did Not Disclose column.
Of course she hung up as soon as I quoted this publication.

This call was SUNDAY night at 8:14 pm
