He was first than me, and for such he picked my champion varus and wanted to trade.
When my time come he started saying random champions that were banned. I thought he was just joking around, but then he said one support and I picked it.
We couldn't trade, because he didn't have that champion. He trolled me, made me start a ranked game as a yuumi midlaner. I left the game.
Am I getting banned for this?
