Is this false advertising?

[James]

I took a subscription out with Great Magazines, on the promise that I would get a free copy of a game I wanted. For months it didnt turn up, and I made a complaint. They then said they would get the game for me following the complaint and it would be here in 28 days. That was a week ago, and now, after me emailing them, they have offered a game I already have, saying they have run out of the game I ordered! Is this false advertising, as I feel like i have been tricked into subscribing
