Longmont, CO number claiming to be calling on behalf of the Colorado Police Force fundraiser or something like that. Sounds like you're talking to a real person but after a few back and forth exchanges I'm pretty sure it's a robot with automatic (but convincingly pre recorded) responses. When the bot started repeating itself with the responses it had already played, I hung up because I didn't want to go in circles with it all day. They were asking for money, number is getting blocked.
