Sorry that it didn't work out :/
The card you bought are known to work very well. My friend has one and only had one issue: had to reinstall macOS, because, idk, just had to. All his files were saved, no problem what so ever. WiFi & Bluetooth works just fine for him!
That card should sell just fine. List it as "New other (see details)", since it's brand new, never used. (You bought it new, right? Eh, who will know... hehe)
