I got a call from this number, it rand twice and then they hung up. I called back and it picked up on the 2nd ring aqnd then hung up. An hour later the same thing happened with these numbers: 213-250-3421 and 213-250-7106 so Im assuming its the same company.

Got a call from this number again today.  Caller ID says it is "213-250-7399 Robinson Associ".  I'm not familiar with this number or company name. They've called twice before in the last couple of months.  My answering machine picks up but they never leave a message.
