Chargeback if you can't get a refund (like me, I bought on Origin). I called up Amex, identified the charge, told them EA misrepresented the product, and a day later I had a credit on my statement. Took three minutes.
I may have been willing to wait out the launch fiasco, but when EA reps explained to me and others that our Origin account would be BANNED if we issued any chargebacks...that was the last straw for me.
I'm sort of hoping EA does ban my account. I'm sure my AG would love to hear about how they no longer provide me access to games I purchased in the past but they now no longer think I should be allowed to use.
Someone, someday, is going to challenge this. Its one of the many unanswered legal questions we have with licensing and ownership rights.
Possibly over-reacting, but I hate it when people use underhanded tactics like this, and I'd be ok with losing my other games just to spite them.
Sadly, I don't own any EA games, so I can't do this.
