Accidentally deleted listed items which contains codes and I cannot retrieve them.

Hi everyone
I recently listen an item titled " 2X $25 ITUNES USA GIFT CODE ". The item was bought but then the seller cancelled as his purchase was under review, before the buy was complete. However after this happened I then deleted the listing and intended on making a new listing with the same codes, however when I enter in the same codes during the listing process its says these codes are already in use on another item, meaning my item I listed then deleted still has those codes attached just sitting there unused. This means I am effectively unable to use these codes :disappointed:.
Has anyone also done this stupidly, and if so what should I do.
thanks. Oli

I’ll PM you about the matter.

I sold an item but deleted before I could mark it as sold. How can I receive the money??
