I don't answer the phone unless I recognize the number or the name of the caller. even though I have been applying for jobs and do expect unknown phone numbers to call me. I figure if it's important they will leave their name and a phone number and a message.  Someone called me from this number yesterday and I didn't answer. They did not leave a message. Then I kept getting reminders on my phone as well as on my TV screen to call back the number. I decided to Google it and find out about it first. I'm really glad I did. Now I see a lot of people have received a call from the same number and it's not worth it to call it back. Thank you
