Who called from 8186685304

Missed the call; no message was left.

They just called my cell a few min ago, just before 7PM. I answered, nothing.....

Called my cel, left no message.

The cid showed "unknown name" and phone number 818-668-5304.  Voicemail captured a recorded message about a survey and free cruise to the Bahamas (a message I've heard under many different phone numbers).
Don't answer.  Don't talk to strangers.  Hide your money.
