Another idiot telemarketer calling and hanging up. Looks like these people have a hole in their head that has allowed all the brain cells to ooze out so the morons can't think.
besides these spammers using caller robot units to verify "valid" numbers, they also find numbers in online advertising. There is no consideration about DNC or someone's privacy, etc. Even the credit apps being used today make it mandatory for one to subject themselves to all types of invasive advertising through any contact info that is provided on their unilateral contract paperwork. This has all come about by the younger generation thinking up new ways to blast the public with all types of useless advertising. So the tech bots want to play games and be connected with all sorts of toys and don't mind the world chasing them around electronically. I've heard even the younger tech group complaining about their being barraged with all types of advertising on their phones, iPads, home computers and anything else they have - but they don't stop to think that it was their idea to dream up this pursuit by wanting to be constantly online. Can't even go to a family function or other event without seeing these people with their noses buried in their cell phones and never having any form of human interaction and carrying on a conversation. I can hear it now: "D U evn no ppl got ears?" "No...rly?" Etc, Etc, Etc....
