Who called from 3235432421

Just got my first call from (323) 543-2421, but something tells me it won't be my last. Caller did not leave a message.

I have received at least 20 or more calls from this number.  No message is left and the calls come at all times of the day. Sometimes twice a day, but not everyday.

I have received several calls from this number, no message has ever been left, and when I pick up, the caller hangs up on me.

I also received a call from 323-543-2421. No message was left on my voicemail.
