This random person will not stop texting me

Some 320 number (Minnesota area code and I live in New Jersey) keeps texting me and they will not stop. At first they sent me a text "Click itwww.lawnlovers.weeble.com" and then "or die" so I said "who is this" and they said from Instagram (by the way the link is harmless it's just advertisements?) and it's not from my personal Instagram apparently (I have a fanpage, don't judge lol). They said i posted my # on there recently and i haven't. I posted on the account for whoever it was to stop. Anyways they won't tell me and I repeatedly asked them and they keep saying random stuff and annoying me I keep telling them to stop but they don't. Also as I'm typing this they just called me but I denied the call. And they just called me two more times.

What can I do about this? Don't say block the # because I'm not sure it's possible on an iPhone (4) without hooking it up to the computer, my computer broke.

Ignore them. Eventually they will get bored because you aren't responding.

Just ignore that person or play along with that person, he or she will get bored eventually.

At the risk of saying something you don't want to hear: block the number.

Stop replying. Or have a guy call them and pretend to be a police officer, that's what I did once, seemed to work. BTW never click on random links people send you 9 times out of 10 it's a virus.

I think you should block the number and the account and it is possible to block a number on the iphone 4 you can research it or call your provider for help

You can try to call the cops, or at least threaten the guy calling you that you will! If it gets down to it, call the cops. They will make sure he stops! Can you answer my most recent question?

Annoy them more… Hell, creep the sh*t out of them! They'll back down eventually.
