I apparently called this # as an outgoing call, my bill said Belgium. The 323 area code is apparently Hollywood, CA or central Los Angeles. I have never called this number. I would like to know how to block this number. I never talked to anybody, or they never left a message, quite a mystery.
I got 3 calls from this number at different times today. I came here and read the comments. I just got another call, answered and said "FBI Los Angeles Division, Agent Smart". There was a pause and then a woman asked for a Mr. Smith. I told her she had the wrong number and she hung up. I hope that puts an end to it :).
