Problem with find my iphone on icloud
I bought another iPhone 4s with find my iPhone on, after contacting the owner, she said she cant remember her password and at the end, she was able to retrieved her password. but the problem now is after we try to log in to icloud.com, icloud didn't show find my iPhone. in the settings on icloud, it can only show some information and there is no traces or any information on find my iPhone let alone able to delete it.
I don't know what to do
