Keeps calling. Who is it?

Just called me.  Didn't answer, and no message was left.  Wish these undesired calls, that happen all day long, would stop.

Called at 8:15pm, CID read "Houston" and the phone number.  We don't know anyone there, so I blocked it as it was ringing.  Positive that it's yet another phishing scam.  Save your sanity and invest in a good call blocker, folks.

Called, answered and they hung up

Called... no one there... blocked
