How can I return the game and refund the money?

[kpapik]

I bough the game via Steam. Im playing singleplayer and for the second time the game AUTOMATICALLY installed patch without an option not to install it. My save positions are AGAIN not possible to load.

I was playing the game on hard and it take a while to finish the level. I dont want to start from the start AGAIN.

This is so lame that I cant really believe its happening.

I WANT MY MONEY BACK, I DONT WANT TO PLAY THIS CRAP.
