Calling back gets recording, "We're sorry, we are unable to take your call at this time...blah blah blah." Note: they NEVER identify their business. That's a clear indication of a SCAM. A legitimate business will identify itself on its voicemail message. Block the number and forget these scammers.
Caller named John claimed to be from some Police Benevolent organization looking for donations to help police families. I tried to ask questions and he just rambled on as if reading from a script. I just hung up.
