I keep getting death threats, I think from an estranged family member. The calls are to my cell phone and from private. How can I find out who it is or stop it?

If you have verizon, you can call Verizon's unlawful call center, but I would just call the police, if they are death threats, you can have them attempt to trace the call and get a no-contact order, restraining order, or possible even press charges against whomever the psycho is.

Call the police.

I get the same thing
honestly change your numbur
it savesz a lot of time
and for prank callersz
they can only prank you if your scared
have fun with them just as much as they are with you
play a long till they get bored n hang up =)

I've done it a lot
or copz are the next best thing..

Change your number

Because if you find out the number and block it then if they're really intent on getting to you they'll just go ring you off a phonebox
