How can I log off the old apple ID and on to the new apple ID in Settings icloud?

Question

I have an old apple ID that is currently signed into my new iphone5s under settings>icloud.
My new apple ID is signed in elsewhere on the phone.
I cannot sign out or delete the old apple ID account because I do not know the password.
I cannot reset the password because i do not know the email where the password is being sent.
I cannot reset the password via security questions because it is telling me the date of birth I am entering is incorrect.
I have no idea what to do now.
Please advise.

f you still have access to your old email address, go to https//appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID.  Tap edit next to the primary email account, tap Edit, change it back to your old email account and verify it.  Then edit the name of the account to change it back to your old email address.  You can now use your current password to turn off Find My iPhone on your device. Then go to Settings>iCloud, tap Delete Account and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud).  Next, go back to https//appleid.apple.com and change your primary email address and iCloud ID name back to the way it was.  You can now go to Settings>iCloud and sign in with your correct iCloud ID and password.
If you don't have access to your old email address, you will have to contact Apple to have them reset the password so you can disable Find My iPhone and sign into your iCloud account.  You can either go to https://expresslane.apple.com, select "More Products and Services", then "Apple ID", then  on the next page select "Other Apple ID Topics", then "Lost or forgotten Apple ID password" and click "Continue"; or you can contact Apple Support (http://www.apple.com/support/icloud/contact/).
