I also received a call from this number. They did not leave a message. I did not call the number back because I do not know anyone from NJ and if it was important they would have left a message.
They have called a few times within the last couple of days. I have both answered and have not. When I answer, nothing is said and I get hung up on. They have called both my work number and my personal cell phone, both of which are on the national Do Not Call list. When I call the number back, it says "The Google subscriber you are trying to reach is unavailable. Please leave a message."
