If that's the way you really feel, I would expect there is more than one jurisdiction where you are entitled to a full refund by notifying the seller within a year or more of being deceived, and if the seller does not rapidly comply, you are then entitled to file a legal claim for 3X the amount, from which there is supposed to be little defense. You would have to check with an attorney experienced at handling Deceptive Trade Practice cases. This is not nearly as serious a violation as actual fraud, and intended to be much easier to substantiate a claim, provided all the rules and deadlines are adhered to. You would probably want to ask for a refund as soon as you could after finding out you had been deceived, and make sure you had an impeccable paper trail. It may not be easy to find a lawyer who would take action with only a 3X upside of what you paid, maybe that's what class-action is supposed to be for?
