Someone sold me an NZXT Flex PC
I was looking for a pc on facebook marketplace and bought one, and 3 weeks later I turn it on like I usually do, to see that Fragile restricted the PC and I'm unable to use it, and that the person I bought it from owes money on it.
Now I'm out of my money, and when I texted him about it he blocked me. And the PC says that I need to return it to NZXT.
What do I do? I'm probably not getting my money back but how do I return it to NZXT?
