They called me 5 times in less than 2 minutes. I knew something was up because Anaheim, CA does not, I repeat does not, have a 657 area code

Using these numbers 4083870397, 2132575233, 8587166364, 6572201614

I knew it...another scam.  I always look up these hang up calls I get, even if it says "Unknown Name" like it did for me.  There's always a chance it was just an innocent wrong number in that case, but I look it up anyway.  A person wouldn't call the wrong number twice, or call other people by mistake as well.

Seeing all these posts mean it's one of those scam calls.

I've gotten calls like this before from a lot of different numbers.  I've never answered them and there was never any message, even a recording.

This one came in around dinner time, so I figured if not a wrong number, it was one of these crap calls.  When I saw the ID I hung up on them since I don't know anyone with that area code.  It also looks strange, I never heard of 657 for CA.
