I am in the UK bought a CD key for a game from a popular CD key website. I am not sure where they're based.
I have done this many times, with many games/websites and since they're well known websites, I have never had an issue.
I had to activate the game using a VPN (which worked fine) but on this occasion, to run the game, I needed to run the game using as a "non-Steam game" within Steam.
Due to this, I can no longer get achievements.
I consider achievements part of the package/product I have paid for.
There was no mention of this on their website (and they've confirmed this on their Facebook page).
Do you believe I am I entitled to a refund?
