Who called from 4243793633

Called and did not leave message. Caller ID says Los Angeles area. Called it back and just got busy signal. Possibly a scam.

Called and left no message

Caller did not leave message, I called back got busy dail tone, I BLOCK all calls like this one.

4/5/17 12:06p Eastern. Received a call from (424) 379-3633. The number was identified as Unknown. No message left = number blocked

I don't answer if I don't know who it is. No message left. Obviously another scammer or sales call. Caller blocked. Makes me mad I have to block 1 or 2 of these every day now on my cell and again on my home phone. Do not call lists are a joke
