Who called from 9722536700

Called and disconnected once I answered.

This number calls almost daily and hangs up. When I hit star 69 it answers with no voice or comes back private.

This person calls most every day, but today is the first time he/she has whispered. It sounded like a man but too low in tone for me to be sure.
When I called back,it was busy. The id has unknown, but the # is (972) 253-6700.

This person also called me, but my caller ID says Community Event

This person calis in the morning and in the evening its so annoying
we run to the phone and no answer. I do a redial and no reply.
