Ok, so you bought and paid for a 16GB card, opened it, and got an 8GB? I can tell you that you should try to get your correct purchase. How much did you pay for the card? And what retailer did you get it from. Depending on the retailer, for almost all, you just need to explain what happened, provide the card and your receipt and they need to take the hit for that. If you have any shreds of the packaging left at all, something with barcode or anything that shows it was a 16gb card, take it in too. Also, I've gone through thousands of SD cards in my retail experience, and I have never seen a card mispackaged like that. Especially one of such high capacity and retail value. If it was packaged wrong, it was because the store repackaged it wrong. But, all else, you definitely need to go have a talk with the manager. If he won't do anything, which I'd doubt, go for the district manager if it's important enough to you. They can authorize just about anything.
