Not only will they NOT remove your number from their list, they'll be sure to call you even more. And to sell the number to their scamming cohorts. I had one tell me to just sign up and they'd stop calling. Seriously, why would they think anybody would "sign up" with these tactics?
So Brian, why don't you provide us with their actual NAME? I'm willing to bet with the name and a simple Google search, a lot could be learned about their "cool" business.
Google is the biggest problem I've had since I got involved with them by downloading Chrome and establishing a Google account. My email spam has quadrupled per each account (4) in the past 6 years and my phone scams have gotten to bad that I no longer answer the phones. google is the worst investment I'v eever made. Worse than Wang Stocks
They aren't actually Google, they only want you to THINK they are. When pressed - hard - they will usually (not always) admit they are a "Google partner". I'm guessing Google doesn't take steps to shut them down because hey, they do generate income, even if they do it in a harassing way. They are all scammers, every last one, and I've been told most of them barely know how to set up a proper Google AdWords, etc. campaign. They're in it for the numbers (dollars and customers signed up) rather than the actual end result on behalf of your company.
