You must consider when picking unsubscribe, the only choice available in your Facebook profile is the disable account, something that makes sure that everything is entirely eliminated, so it might be that the pictures, remarks and private discussions are kept, although already not be available to them.

http://www.facebook.com/help/contact.php?show_form=delete_account
Note: As soon as confirm not be able to recuperate your information and everything to do with the Bill, currently not you can use functions it email, which offered low, you would have used a new account hotmail, gmail, and so on.
Erase demand from sent out by mistake
To erase a request erroneously sent to an individual (e.g. request for friendship) in the leading menu go to "Configuration", then "Personal privacy settings".
Then write the full name of the person in the field "Block individual".
Then look it up and lock it. So not your friendship request, will be because blocking somebody eliminates any link with it. If you desire this individual to find you or have contact with her, you go back to the 'blocked list' and remove it by pressing Delete (but currently not your application will appear to him due to the fact that it was formerly obstructed).
This does not work for sent messages, since they are all stored in the Inbox of the individual.
Thus the article Facebook Account Delete from us, hopefully useful thank you.
