scam caller

Calls and leaves no message. No 800 notes on this ID yet, but Google Update scammers associated on 800 notes with some or all of the numbers listed below. These were all encountered, logged, and tracked within the last 14 days and it is obvious they are from the same spoofer/scammers. The internet is loaded with complaints for this 213-298-37xx format. It should be a really easy target for regulatory crackdowns.
213-298-3756 Los Angeles CA
213-298-3757 Los Angeles CA
213-298-3770 Los Angeles CA
213-298-3779 Los Angeles CA
213-298-3781 Los Angeles CA

Also the fact that in Skype there appears an added "1" in front of this phone number, so 12 digits total. For this or any string of caller ID numbers, this is always a dead giveaway of a spoofed number originating from overseas.
