Well, it's your right to write to the support service. But know that I am not a game developer and have nothing to do with this. I received the keys and gave them away, a year has passed, what claims can I have if the game developer himself withdrew them. When buying games on third-party sites other than steam, you also write to the support service if the key to the game was taken away from you, as it was recently with Redout

Yes, of course, unpleasant events for both you and me.Especially if you have already received achievements and successes in the game. Try to contact the game developer and give him your opinion. Good luck to you and enjoy a sunny day, and don't worry about any little things.
