I usually pick up the phone but do not talk,I'm sure they'll not ask hello,and when their robot starts talking I simply say 'this number it's out of service" in a robotic voice imitation. thye stopped calling after a few tries!
Called @10:40 a.m. today. Picked up the phone, no one talks. I hung up. Caller ID says Unknown name. No use trying to get my name of the list of these fraudulent calls. They use different IDs and still keep calling. Sometimes I don't answer. This number is added on my "DO NOT PICK UP THE PHONE" list.
