Hey there!

Sorry to hear you're having trouble redeeming your code. For code redemption issues please run through

this troubleshooter. If you're still having trouble redeeming the code then I'm afraid phone support is going to be your best point of contact. Apologies for the confusion!

Hi there,

only the store that sells it can activate it as far as I know, sometimes it takes 24 hours for the store to process the activation.

This is a snippet from the support page

This code wasn't activated by the retailer. Contact the store and have them activate the card

All codes must be activated at the point of sale in order to be used on Xbox Live. Sometimes there can be a delay at the retailer when activating. If you receive this error message, wait 24 hours and try again. If the card does not work 24 hours after purchase,
take the card back to the retailer along with your proof of purchase and ask them to activate it.

So it seems the only option you have is to return to the store again to have it properly activated.
