Q: billing

You already know that you are only talking to fellow users on these forums and that iTunes Support are not here.

What do you mean 'bills are to be closed' and 'close out my iTunes account' ? iTunes accounts can't be 'closed' or deleted, you can only remove personal info from them and stop using them. If you mean remove payment details from an account then try logging into it and see if you get the 'none' option : Change or remove your Apple ID payment information - Apple Support - or change the password(s) on the acocunt(s) via http://appleid.apple.com so that nobody else knows them
