I just purchased the mystery box that was advertised for 9 yocash, and was charged 18 yocash! I have submitted a ticket, but do not anticipate a response for at least a week. Just putting out a warning to others
Mine has been refunded for the over charge, check your YC transaction log as they haven't yet got around to replying to emails but are doing the refunds Thank you
