I'm from the UK though it's totally different
Do you have any family in the states? Friends who could report it? Ask your parents, do some research, call your local police and ask what would it take to file a report on an online scam like this, do fucking something. And in the end, even if they can't do anything, you atleast gave a fuck, you actually asked, you did something, you gave a shit.
i think telling his parents would be the worst. theyd probably flip the fuck out knowing their kid spent 600$ on a jacket HAhahahaha
