what do i do if i accedentally bought a iphone 5c off the darknet?

[Terrauser]

i went on it for the first time and now i don't know what to do. it said on the page that my order was placed. i didn't even mean to click it. the site was for onyx or something

i'm terrified, are they going to make it and bring it to my house? do i tell my parents?
i did not give out any personal information..
i didn't even type anything, i think it said order confirmed and then next to it it said address: and a bunch of numbers

Did they get your payment details, address, etc.? Because without these details, they'd have nowhere to deliver the product or receive the payment.

And if they did, well putting personal information on the darknet was probably the biggest mistake you made, regardless of the iPhone or not.
