No message left by these idiots. I let the machine pick up, and they hung up after the message started playing. I assume it's the same company in a boiler room using software to spoof the caller ID.
Called today, left a VM saying he'd "made a whopping $40,000 in his first month"...doing what, I have no idea 'cuz the robo voice started talking before the VM beep..but it has to be another get-rich pyramid scheme.
