Getting banned after quitting 1v2 Doubles

In three out of the last five matches, I was placed in a doubles match without a teammate. Why does the game expect me to face two people alone and die a total of 75 times with only a handful of kills? Why am I now banned because the game is screwing up? This seems really messed up.

I just had the EXACT same thing happen. Quit on the third game, then got banned for 12 hours. I was banned about a week ago for quitting a 4v1 game as well. This needs to stop.

It is really painful. This happened to me a lot, and I feel the need for this to be addressed.
