I just got a call from this number they didnt say anything it's weird

I just received two phone calls in a row. I answered them both and nobody said a word either times. Don't really know what this number is or why they are calling but it needs to stop.

Have gotten 4 phone calls this week in the early am hours from this number.  No one is saying anything on the other end though. It kinda freaks me out and it's also getting very annoying!!!!!!

I got a call from this number saying something about Saw and said my name too

They called me and said 9/11 was gonna happen all over again...only it ill be worse..what an a***ole.
