Initially i though OP simply mention wrong domain on the email address. But it turns out someone already own domain freebitcoin.in[1] already exist.
Not your keys, not your coins, applies here. You and I have no control, and any resolution is going to come from getting in touch with them.
While i agree with you, i expect many freebitco.in user wouldn't do that when freebitco.in give some reward[2] for user who buy and hold FUN token on their website.
