Got a message that wasn't from my carrier's default automated message saying "This number is invalid. Please hang up and try again."

Multiple calls daily from this number with no one ever on the other end.  Is there a way to block it?

I want calls to stop

Got two calls from this number today. The first was just "dead air" when I answered. The second call had some guy with that "India" accent asking personal medical questions. Told him that I do not give any type of medical information to anyone, at anytime over the phone; especially when they won't tell you who they are or what they want. Told "him" not to ever call me again, have a nice day and then "Goodbye"!  Hope this helps someone else.

Call from 720 403 9684.   No one there, they call freq.  want it stopped.  I am on no call list
