This number (571) 319-5622 just called with no message.  Idiot!

Some spam call from a company trying to sell you a car warranty.  They identify new car purchases and begin calling as the factory warranty approaches expiration.

Caller hung up as soon as I said hello.

Just received a call from this number. Did not pick up. They did not leave a voicemail. I suspect it's a spam call. I added to my reject list. I guess our phone providers are selling our information to these scammers. Very lucrative business for phone companies. Dam you all to hell.

Since you did not pick up the call, and the caller left no voicemail, how do you know the caller has your name linked to the phone number?
Many scammers simply cold-call every possible number in an area code + exchange.
Or the scammers are using old telephone books of residential numbers.
Remember telephone books?
