I do not know who this is calling me so if this number shows up on your phone please do not answer it because it might be a scam.

Just got a call from this number and when I called it back a man answered and said, "Thank you for calling the American Vets Assoc."  Never heard of it and I get calls from all kinds of supposed charities.  However when I want to give to any charity I do so when they send me something in the mail that I can verify before handing over any money.  The only way to give over the phone is to use a credit card and I will  never do that too easy to be scammed.  I did get a request today in the mail for the Disabled Veterans and they always use VETERANS  not VET.  

annoying calls from 240-650-8687

Got a call from this number and the caller ID said Silver Sprin MD. There was a very obnoxious man on
the phone saying he is from the American Disabled Vets and for a one time donation...blah, blah, blah.
When I told him no he insisted on a $15 donation and started to get nasty. I politely stated I was not interested
and hung up.

It's an automated system when you call back trying to simulate a live person. You can confuse the automation robot by asking completely unrelated questions but it is pretty good about recognzing words in your sentences and forumulating a reply based on that. But his is for sure an automated system attempting to trick you into thinking you are talking to a live person and yes they are looking for money and credit card details.
