I purchased 50 Black Diamonds from GTArcade and in my History there is a record of that confirmed purchase - I took a screenshot of that as proof of purchase - But in game I have no idea what screenshot needs to be taken - I took a screenshot of a System Mail acknowledging 50 Black Diamonds being received and that was rejected - I took a screenshot of my Black Diamond Info showing 50 Black Diamonds and that was also rejected - Besides the system mail there is not a place within the game that would retain a copy of my purchase

What screenshot is needed that is in game?

Thank you
