Someone is harassing me from this number

same here, no message

Says it's a security company promising a free security system but never calls back

Cell phone rings from a number (this number) I don't recognize so I don't answer. After four rings they hang up and I check the number on Google. 800 notes comes up and I know it is spam so I add it to contacts with a name I will recognize so I won"t have to bother if they call again from the number.
