In the future, we will introduce functionality for code deletion on the Gift Cards tab and an option to reduce/add balance from a customer page in the admin area. However, we do not have an ETA on this. For now, the steps below are the workflow to revoke a gift card in the event the purchaser disputes the charge.
You have two options.
The first, is to wait until an end-user redeems the balance, then write into support and request that we remove the balance from their account. Please provide the end-user email address and the gift card balance that was applied.
Or, an admin on your site can redeem the code.
To do this, click on 'Storefront', then click on the equivalent of "Dashboard" (/dashboard) - which you may have renamed in your top navigation to be anther term.
Redeem the code.
The redeemed gift card amount will be added to the the admin's balance. You can either leave this balance alone and do nothing further, or if you really wish to remove the balance, please write into support with the admin's information and the amount to remove.
