Two Sentence Horror

The Call📞

I was babysitting for my neighbor's kids when I got a phone call "have you been up to check the children"the man on the other end of  the line said.  I assumed it was a prank call so I hung up. Then the phone rings again "Have you been up to check the children" I hung up starting to get genuinely scared so I called the police they told me if he called again to try to keep him on the line and call the police. So when the phone rang again I called the police then answered the phone "I've taken care of the children now I'm coming for you" then he hung up. I pick up the phone I called the cops with and they told me this "Get out off the house now the call came from upstairs!"
