Its happened half a dozen times now and its frustrating as I keep getting charged for listings I do not want to have active. Please fix
@TinyFeat: "Please fix" Just so you know, even if Etsy Support or the Help Pages sent you here this is a seller peer to peer forum, and should not be considered a way to contact Etsy, if that is your hope (although Etsy does sometimes read and reply to posts).
You should try https://help.etsy.com/hc/en-us/requests/new?segment=selling or https://help.etsy.com/hc/en-us/requests/new?segment=selling#issue_sell_manage_listings-callback or you can open a support ticket through Dashboard > Community & Help > Contact Us
Do you have old listings set to "automatic renewal" rather than "manual renewal"? If so Etsy will renew those listings as they expire.
Just a thought.....
If you deactivate a listing you must remember to also change the renewal settings to manual, then when the current listing period ends they will expire. If you leave them set to autorenew, they will keep renewing every four months, even though the listing is not currently active.
Have you checked the update mode of the listing? Is it automatic? If so, you can change it to manual.
