Received a call, I didn't answer and they didn't leave a message. Most likely another scam number. I Googled the number and a site came for a Silver Tech Support: http://heavensoldier777.wixsite.com/silvertech/contact
Based on that link, and that it says "heaven soldier 777", definitely not a number you want to answer.
Called my cell - I didn't answer (of course). No message left. Called their number back from my office's main line. It has a *blip* of the busy signal and immediately the line is cut and goes dead. So, this number doesn't exist and is complete and utter spam. Don't answer if it calls you. There is zero point.
