Phone # 323-372-3064 is a spam calling system. They call you and when you say hello they hang up. Robo Calling. Just put them on the black list and problem solved.
Call from this number on my cell phone May 7. Friends and family have distinctive ring tones. When I hear the carrier's default ring tone I look at Caller ID. If I don't recognize it, I don't pick up, it's that simple. But it is still annoying!
