You should be ashamed of yourself, don't you think that posting something so obviously wrong, when everybody here knows we always fix these sorts of mistakes with no issues, will make YOU look like a fool?
You emailed about this in the middle of the night of the 21st, and you haven't even let the customary 24 *business* hours that are a very reasonable standard before posting this on the forum.
Of course, you'll be refunded the GSX for FSX you bought by mistake, and you are so wrong to use this tone and, again, everybody here knows we always support users making these kinds of mistakes, that I almost feel sorry for you.
In fact, about the other blatantly false statement you put in this post, that we "deleted posts of people", might have helped you in this case: if your posts were really deleted, it would have saved you from this embarrassment. But I'll keep it here, and a future memory of how WRONG some people can be, and there's no limit to that.
