hello i am gory and i got scammed on rocket league

Basically i was trading 4 keys for labrymith, and i accepted how ever with 1 second to go it dispeared, i found out i was scammed with the technique of someone adding and quickly removing something and because of slow connection that item stays there then at the last second it was revealed to me it wasnt there but it was too late, so thats how i got scammed, if you can donate please do it. ty.
