Who called from 4156206219

this number called me, did not leave a message, but showed on caller id San Francisco

I received a call from this number, no message left and when I tried to return the call the number is invalid.

This number called me before noon CDT, did not leave a message, showed on caller id San Francisco.

We receive calls from this number, we say "Hello", and they hang up. We do not know what company or who they are because they hang up when we say hello.  Please make these people stop their harassing, prank calls!!!
