Last week I got a call from this number identifying themselves as from the State Police asking for donations (SCAM) Yesterday got another call from this number but this time they said they were calling from The American Veterans Assoc looking for donations When I questioned the caler he swore at me and hung up SCAM
So your instinct was right. There are many places that list themselves as American veterans' associations, but if they don't like questions, then hang up.
