This number called me today and I immediately hung up. Then, worried that it might have been a legit call from a client, I called back only to hear a recording asking if I wanted to be taken off the call list. I hung up and blocked the low life for good.
These [***] were trying to say they were Google Local. It is a robo-SEO company calling for leads. Not sure how they got my cell phone number but [***] them.
They think they're pretty clever. If you challenge them at all, they just hang up on you. If you call back (using the caller ID) you can't reach a human, you can only (apparently) add your number to the do-not-call list.
