you were most probably banned for being AFK.
People need to understand that if you are playing deadlock right now you are acting as a tester to give data to the dev team. What they want is for you to actually play games so they can gather data and test implementations.
If matchmaking is frustrating? play the game, leave your feedback in the forum, then go back to play.
If you quit because the game is unwinnable (even if it's true) or you stay AFK in base for the enemy to "finish fast" then you are not giving them the data and might even be skewing the results making it harder to tell if their changes are working or not. This is why you were banned.
We were invited to to play because they want us to test the game. We are not here as players, we are volunteer testers.
