How do you undo the 'Mark as sold' option for your listings?
As of now, we do not support undo-ing of the 'mark as sold' feature. This was because we thought to give sellers and buyers a glimpse of a user's track record of sales.
In the meantime, we understand that accidents or misunderstandings do happen and the 'Mark as sold' button is tapped accidentally. Do write in to us at firstname.lastname@example.org and we'll be happy to help you to manually reverse the mark as sold action.
