Any real bully doesn't threaten they just do it, so report it or take it upon yourself like I did and call their bluf say nothing and beat them up... It got me in a lot of trouble, but no one bothered me after that.
Tell a parent/carer/ friend/teacher. Also, call the police so they can stop you from being in any danger.
If you seriously feel threatened and fear for your safety you need to alert the police. And don't be afraid to report them to the police, cause they have problems obviously if they are threaten you. And if you are in school, tell your principal and have them keep a eye on you! good luck
Hurt them enough so they will not want to tangle with you again.
I just got Threatning from three girls that hate me! & I'm callin the cop's!
You should tell your parent or you should call 911 so that they can take care of it
