Who called from 9893726512

Called, no message. Caller ID said BCOF.

I didn't pick up for this number so the called back with (951) 355-0101.
If they were honest they wouldn't risk alienating people using multiple numbers and harassing people.

This number called the office two days ago. I have no idea who/what is was, since initials can stand for anything.

I wish they'd stop calling and interrupting my game of Clue. Don't answer, they don't leave a message. If there's no message, it's not important or real folks. Don't answer the calls you don't know.

This number calls about 30 times/week.  They ask for me by name but don't leave a message
