I just got a message from that same # about an hour ago.  I tried calling back.  After waiting a minute or so, a message came on saying "you have reached the corporate office, please leave a message".  They don't say the corporate office of what company.

I just got a call today and tell if your name is Brian dial 1 if not dial 2 no name or anything I called back this number and put me on hold.

A man with a weird voice left a VM - "Trying to reach you regarding serious legal matter than you chosen to ignore.  I need to hear from you today.  I can be reached at 213-634-7550."

Upon calling back, it goes to an answering machine.  What a bunch of losers!

I received the same message as above, it is annoying same results as above.  How can you stop these calls.
This is the third time I received such a call.

(213) 634-7750 - I got the EXACT same message as those above - from the dates - they must be busy little scammers!!! Called in and was sent to an answering machine.
