Called and I answered but nothing at the other end.  Blocked in Google Voice now.

This number belongs to a company called Xoka Inc. They have called me several times before from a different number. This is a scam. They try to mislead people into thinking they're Google to sell unsuspecting small business owners a listing on Google's front page. Google themselves warn about this scam, so don't fall for it. I managed to get 2 different sales reps to tell me who they work for, so that's how I know this is in fact Xoka Inc. This company is located at 18582 Beach Blvd #200 Huntington Beach, Ca 92648. If they don't stop calling, let their local police department deal with them

If you really want to have fun, try this.  If you know the number is from a scammer, answer the call;
"FBI, Agent Turner".  That will scare the idiots off.

i did not answer. I called them back and I receive a txt saying that he was at the classroom. ThenWhen I call them back  the second time
they put an answering machine for www.pinger.com

No one there when I picked up.
