Don't answer. Block CID on call back. It's an auto bot/auto record "Hello? [pause] Hello? [pause] Okay, there's no message I'll just try back another time."

I just had my number changed to a number I used to have 7 years ago and has not been recycled. Has been inactive for 7 years. Within hours of the number being activated, and requested/confirmed that number is unlisted, we began receiving auto-bot/spam calls. This is the fourth call in two days from auto-bot/spammers. Coincidence? I think not. Thanks TIME WARNER CABLE for selling my phone number. Liars.
