I suspect (from #3 "pc" and #6 "My Computer") that this person is running a Windows box. Given how poorly stated the post is I'm not going to bet on it. No wonder the Kobo service boys have taken over two weeks and have a "lack of understanding".

After reading the post three times I suspect that the person has a certain quantity of books showing on the Kobo and no matter how he/she tries to add books or delete books from it those books are neither added nor deleted. But it could in the end just be a recipe for chicken soup for all I know.

How about re-listing the 9 points in paragraph form rather than Twitter "tweet" form?
