Heronext bought comic from Worldwide via credit card.
Comic shows up damaged.
Heronext sent comic back to WW.
WW sent refund via check for some reason, inferring that they agreed to refund.
Heronext decided he wanted comic anyway and sent back refund check instead of, I think, confirming with WW that he was going to send the check back. Destroying the check was never considered apparently. Communication between the parties is fuzzy here.
The check is currently floating in the void somewhere.
WW, likely done with this whole transaction and annoyed with the comic, sent it off to auction. Not great.
Currently, Heronext awaits the refund.
Obvious solution: WW cancels the check and refunds the original payment method, which is a credit card.
