I posted a comment here a year ago basically saying "don't get your hopes up for this one, the devs have a bad reputation" and unfortunately it looks like I was right. It's a shame for everyone who trusted you guys and spent money on this scam.
Y'all, best thing you can do right now is to remember the name "Parival" and avoid it like the plague next time they create a new project to steal money from unsuspecting people.
