I don't answer calls I don't recognize and these people never leave a message. My phone also said it was from SNFC MT EV CA. I worked for the VA for 25 years and know that most of these veterans groups doing fundraising this way are crooks. They keep 80 to 90% of the donated money after complaining how the government is doing nothing to help them. The other charities such as the firefighters and FOP do the same thing. I know because I have called the fire department and police asking about fund raising and this is what they told me.
I took the call as described in the posts above and let the caller make his pitch for a donation. At each point where he expected an agreement I replied "no". He suggested a different form of contribution encouraging me to think of the needs of the alleged veterans. I simply replied "no"..and he said "very well, goodbye"
My point is I gave him no information, no agreement and no donation and I let him spend his time and energy on a "non-response" target
