getting scammed on rocket league proof

this guy was saying he would do a giveaway. how this would work was you trust him with some items and he would give the items back and add something. i was in his party and with some others, he was giving to others but i later knew that were his friends and were in on it. i tested it with some crates and he gave it back with adds. next i tried it with crimson loopers, he took it pretended to invite someone else for the party and kicked me. He has a youtube channel: Littlecatsteps. Unbelievable someone can get 3000 subs while he is actually a scammer
