Who called from 6475557777

I kept getting calls from this number with an automated voice that I have not verified my google location. Finally I pressed 1 and got a human asking for my name. I first asked what company he worked for and why he was calling as I was confused. He hung up. Someone please explain what the point of this is? how can they scam you? How can they get money from you? I really don't see how.

Phone rang.  647-555-7777.  Picked up on second ring.
Me: Hullo.
Them: (silence)
Me:  (after waiting a few seconds) Are you stupid?  
Them (silence)
Me (after waiting a few more seconds)  Do you know how to use a phone?
Them (silence, then a couple of 'clicks' and a busy signal.
Me:  Guess they DON'T know how to use a phone!

Robocall stating we have not updated our Google information - which is complete bullsh*t. Caller ID said "Ontario".  BLOCKED.

Daily garbage calls

I saw the phone number and Ontario. I left it go to the answering machine. Pertaining to my order for Google Ads. I have nothing to do with Google.
