If there is a major deviation from the description of the product I always ask for a partial refund, with the amount asked relative to the amount of deviation from the original listing. I have about a 50% success rate. The other 50% are resolved through a PayPal dispute and I win maybe 50% of those, so overall I am about 75% successful with regard to partial refunds for deceptive listings.

If the seller and I come to a mutual agreement regarding the amount of the refund I always leave positive feedback discussing satisfaction with regard to handling of the issue. If I have to take it to a dispute I always leave negative feedback to let everyone else know the seller is a fraud.

I can't imagine just accepting being gyped by some con artist.
