Hi there @e72ffe91b8a4c317
If you're not able to redeem the code you've purchased, the live support team can submit a refund for this purchase even if the transaction has fully process through- while we aren't able to submit a refund for you here on the forums as we don't have access to your account and billing details, this is something the live support team can process for you.
Please submit a new help request on the site here to have live support process this refund for you- I'd also recommend you attach this AHQ conversation when you reach out there so the team has further information to reference. If you run into any further issues getting this processed, please let me know.
