I don't answer phone numbers with a different area code to where I live. If a call is important enough, I figure they will leave a message and I'll call back. They called me twice and no message left. Blocking.

Telemarketing, annoying called me from three different numbers on same day.

3 calls received yesterday on my tablet. Never given this number out. Suggests it a SPAMMER

If they do not leave mssg - best ignore!
