Unfortunately there's no way for you to prove that you didn't get whatever you chose because you could've chosen a Nymph. I'd need a screenshot of your entire card collection before and after the chosen card, as well as a screenshot of you choosing the card itself in the redeem screen.
However, I've helped others before based on good faith, so if you can send me a screenshot where both the receipt and your e-mail is visible, I can help you.
