I bought a fortnite account from instagram. When I sent the amazon code (25 euro) the user blocked me without telling me the data. I have no information about the buyer! What should I do?
Nothing. You were scored. You gave him the code first and can't do anything. View it as a lesson.
"What should I do?"
Annoy you about your carelessness.
In such "sales" is a lot of fraud.
The scammers know all the tricks to rip off careless people.
And as long as there are reckless people falling for it, the cheaters will laugh themselves dead and keep it up…
Learn how to learn.
Only buy on reputable platforms where you also get the contact details of the other person.
Without anything you can enjoy your naive credulity. It may be fine if the other side is honest, but gradual criminal energies use the possibilities of anonymity.
I would have immediately notified Amazon that the code was stolen and they lock it. Then the other would have had nothing of it.
