You need to be requesting that refund. Publishers do this because they've been able to get away with it for years. Atari in particular has a reputation at the moment for taking established names, handing them off to unknown development teams and releasing half assed crap masquerading as a game in order to make a quick buck from the brand. It's unacceptable, but they keep doing it because it's making them money.
Get the refund, and see if it improves. You can always re-purchase later if they manage to fix and polish the game, and it may even have dropped in price by then.
