It's just the maturity level of the newer players...I've played against someone before that though they were winning, and then when I finally pulled out my control (I was using my god killer deck in PvP because I was bored), they called me a whole list of names, which I won't repeat, and then left game. Don't let it get to you. Just be glad you got a free win, which gives you score, money, and three spins.
