I started a draft game, and the game began without me seeing the mulligan phase.

I should mention that a few moments earlier, I had canceled a match search to make some changes to my deck.
After I finished, I restarted the search, and a match was found instantly. I immediately found myself having to play my first turn (I was the first to play), naturally with a terrible hand that caused me to lose the game.

I kind of feel like the first match search was never actually canceled, and that the game started without me actually being present in the game.

I would greatly appreciate compensation for this lost draft game.
