I don't pick up. This is one of many many "unavailable" calls we receive on a daily basis. I have caller block but phone still rings once.

never leaves msg -

Caller ask for me and when told I'm not there they hang up.

they call asking for my dad once he gets the phone they hang up if we say hes not there they hang up they call like a million times every day....when we call that number back they do not answer
