Some Fake "Google" Company trying to sell you SEO and SEM Marketing.... I would probably listen to a sales pitch but if your calling me pretending to be from Google, well I just became DEAF!
At one time I had over 150 numbers on my phone as SPAM numbers. It was taking up so much memory and they use new numbers all the time, so I just deleted them. Under my cell phone plan you can only block 30 numbers.
