Who called from 6143329020

Didn't leave a message. Called back and got 'the number or code you have dialed is invalid"

Robo-call asking about a home security system.
Delay between me answering questions and their response to my answers.  When I told them no, I was not the homeowner and no they could not talk to the homeowner, they hung up.

Scam company. I recognized the voice of the person I had on the phone (2 weeks ago he was the big bad IRS) and he cursed and then hung up.

Scammer. Robo caller said he was talking to me through a computer. Security system something or other...I hung up.
