I have had the same issue with one of my items being unlisted as "Spam or Disallowed Listing Practices-Item Spam (multiple listings for the exact same item)." However, I am unable to access the listing in any fashion. Whatever I click tells me the item is unlisted, so I cannot see what the listing says.
As we are all aware, in the past there has been an issue where an item's listing has been changed after posting, and i am very careful that each listing correctly identifies the item being sold.
My question is how do i access this listing? I do not see that item listed with the number of items in my inventory, so I believe this is in error, but I cannot get to the listing itself to see.
Please help!
