If you were me, would you delete the game? League of Legends Wildrift Chinese server

Everyone says Veigar is the late-game king, but can he beat a teammate who wants to lose? In this match, I completely dominated Yone in the mid-lane, stacking AP like a monster. But just when we were about to close it out, our Jungler decided to "join the other team." I usually show you guys the wins, but I had to share this one. It's a textbook example of "Electronic Injustice." How do you deal with this? Let me know in the comments if you’ve ever had a game "sold" like this!
