Received a call from this number at 9:14 a.m. this morning. Did not answer and they did not leave a message.
Blocked the phone number.

they called i said hello and no one said anything on other end. i hung up and blocked

Caller did not respond; must have been a robocall.
I've blocked this number.  VK reported the call was from California (Costa Mesa, Irvine, Newport Beach).  That's expensive real estate for a boiler room cold-calling business.
