These people call anytime they feel like it ... even on a Sunday.  I do not talk, just pick up the phone so the answering machine doesn't get it.  No one speaks, but they breath and make a lot of noise.  They don't bother leaving a message if the machine picks up.

They've called 3 times in the past 3 days.  Don't leave a message.  Caller ID says "US Arm For Assn".  Web site says a veteran's support foundation. http://usarmedforcesassociation.org/   If it's really them and not a false  id I guess you can look them up on Charity Navigator, BBB,  or some other 'review' site to see if they actually do a good job of helping vets or keep most of the $$$ for themselves.
OOPS...  Subsidiary of Veteran's Support Foundation. Looked up Veteran's Support Foundation on Charity Navigator. Said only 28% of what they collect goes to programs and services it delivers!!!!   Dump them quick!!!
