Who called from 2139765100

213-976-5100 - Receiving CONSTANT calls from this number. Roughly 5 to 8 per day. I have NO clue who they are. If I answer, they hang up. If I don't answer, they don't leave a message. The calls are coming in at all hours of the day and night, some even as late as 2 AM CST. I'll have no choice but to file a formal complaint with the FCC if the calls persist.

I get call after call from this number...  When I call back I get the message "The call you are attempting to place is not allowed from this line."

It says it's an invalid number when I call it...even though it showed up on my caller ID.  CONSTANT CALLS!

Also getting daily calls from (213) 976-5100.  Sometimes they leave a message and I believe I hear a fax machine beep.  Other times, nothing.  Have not tried to call the number back because it is calling my work phone and I do not want long distance charges applied.
