Robby will NOT reply to you.
If you was banned for Steam Refund, you will remain banned. Don't waste your time.
Helmet Heroes has ZERO moderators. NONE. ZIP. NADA. And Robby doesn't worry about Helmet Heroes. This is officially a dead game by them standards regardless how many people might be on playing.
You will NEVER get a refund.
You will NEVER get unbanned.
Don't spend your real money on this game.
