"Hi, this is Sharon, your local Google specialist..."
No, no it's not. It's a lame poser recording from a company that doesn't work for Google at all.
I despise cold-callers that disguise their company name in callerid, like these guys do.
Look, if you believe the schlock that anyone can guarantee front-page search results, that would mean search engines can be blatantly manipulated and therefore their result listings are unreliable. Hang up, or you deserve whatever crappy expensive outcome you actually get.
Don't get mad, get even. Here is your chance to waste their time, for a change. Put the call on your speaker phone, mute your microphone, and see how long they stay on the line. The more time they waste yakking into dead air, the more you win, and the less time they spend calling other suckers.
