Sounds the same. 1st call no message. 2nd call no message. Called back and got recorded message and entered '1' to stop calls. Called back 2 hours later. They were representing a home security system. The call was from a computer recording that responded to voice. I did file a complaint with the donotcall registry.
I received a call 2 calls today. The first at 10:34 am and then again at 4:01 pm. When I answered the second time, a man said "Hello, this is Tom from Home Security System."
I didn't wait for his sales script. I just immediately asked him to remove my name and number from his call list. He was polite and said it would be removed right away.
