Who called from 3605296156

I got a call from this # today.  The caller I.D. says "PACIFICTEL" which, I am assuming, stands for Pacific Telephone.  I may never know because they left no message.....annoying.

In the past 72 hrs. I have recived 6 phone calls from this unknown #, and 10 mins ago I answered phone ,saying Hello , just hearing a lite breathing ,........  Im in a rest Home , and this is Uncalled For !!    Want this stopped !!           Asap.

Me too, I don't wait long too hang up and don't let it anger me.

who is it or what company

They have called twice in three hours.  No message.  No one there if I pick up.  How do I stop it?
