I DO think you have a leg to stand on. The fact that you can buy directly from the page that DOESN'T say 'Factory Second' even though that particular item IS a factory second, is misleading. How are you to know that one listing that says factory second applies to another listing that doesn't? I would be pursuing it based on that. If you were directed to the factory seconds page BEFORE purchase, that would be different. Does it say anywhere on the receipt that it is a factory second? Or maybe an order confirmation email or something?

I would have assumed they were two different listings, if it were me. Yes they're the same price but I would have thought they were two different items. Definitely pursue it.
