They've called 4x in 2 days. I never answer #'s I don't recognize. No message left. Funny how they always hang up after the 2nd ring. They must have some way of detecting whether or not you have an answering machine.
Called at 9pm. Left no message. Probably a robo caller looking for numbers that people answer. This number has a 100% spam rating. The only other area code 310 number I have received was for the IRS scam.
