Not sure exactly who it was, but something about the homeless. My guess it trying to collect money. I had to say hello 3 times before they clicked on, butchered my name and then I just said 'no thanks' and hung up.
I received a call from this number and I think i was scammed. They claimed they were with American Homeless Veterans and had my last donation info. But the credit card charge was from Circle of Friends in VA. They didn't provide me a TaxiD or other info didnt ask for email to send receipt. Called the bank right away and filed a claim. Stupid me.
