My code has been used already

Hello, or did you buy your card from which card it is and have you checked if what you bought is not already on your account?

Hello,

If you bought a code from a brick and mortar store your best bet would be to return for them to have them fix it.

If it is from a digital store contacting them is best.

If it was directly from MS contacting chat support is your best bet via https://support.xbox.com/en-US/contact-us

On the console, it will only tell you that the code has already been used. It will not give you a date or time. It may be possible that the person who originally purchashed the code can check this though. Did you get it from someone who purchased it for
you, like for a gift? Or from a retailer? I don't know of a way that you can see the time or date that it was redeemed. I think perhaps, only the person who originally purchased the code may be able to find this out.

u tried going into ure download history to redownload it?

The best thing to do I think is try going to the retailer you bought the product from if the code is indeed already used and ask for a replacement.
