Description:
I, Derp Guy, traded Umakiro 6 keys in return for the 3 ghost recon promotional items when they were released. They were since delayed, and just today Umakiro removed me and blocked me, even though the items were to be tradeable in a few days.

Please read the guide on how to properly format a report.
