Is Microsoft stole my game?

I hear where you're coming from. On the contrary the grass isn't any greener on the other side as they say. Sony stole from me in pretty much the same manor but with no offer of a refund, in fact they didn't even feel the need to talk with me. I was constantly
hung up on and lied to. That's a story for another time however. Onto your problem.

My first couple of thoughts as to proof of purchase are, 1) Bank statement and 2) Microsoft account purchase history. Are you able to provide proof of purchase through either of these avenues? If so simply inform Support that you have proof and would like
the game to be put back onto your games list.

If the players don't respond, it will happen... if everyone submits everything to the company, give them anything what they want, it will happen...

They can whatever and player MUST acquiesce?

OK but, without my person.

There are still a lot of amazing independently studios...

People wake up... Why do you let [mod removed] get on your head?

Ok, in this case just stop playing the game.

you own a licence to play the game, this licence can change overtime at will, all games nobody owns you just own a licence for the game.

Waiting for your follow-up.
