Bought an App Store card what to do?

I bought an App Store card worth 50 euro an hour ago…
I actually wanted to buy credit for Playtsation and that's why I reached for the first blue card with 50 euro on it… It was only when I got home that I realized that I had bought the wrong card… Unfortunately, nobody in my family or friends has Apple and I can't do anything with it myself… What should I do now? Can you convert it somehow into Playstore credit (or maybe xbox live) or can I somehow use it for which I don't need an Apple?
I'm desperate…

Only eBay classifieds and selling at a loss will probably help you. The shop does not have to take back or exchange this if it is at fault.

A return or exchange is excluded. You can offer the credit (with a price reduction) on eBay.
