This number keeps calling me, never leaves a message and when I call the number back they hang up or it goes directly into voice mail that is too full to take messages.  Would love to know who this is.

A male voice who identifies himself as "Carlos" is calling my two sisters, one in California and one in Texas, attempting to offer them a business deal. He says he has a "business proposition" for them. They do not know him or recognize his voice. He also has been sending emails to the one that lives in California, so she believes her email has been compromised, since he recently called our sister in Texas from 323-215-1229.
