I'm afraid that if you have a used phone which has been Activation Locked by the previous owner, then only he can unlock it, either by providing you with the account ID and password, or by removing it from his list of devices (as should have been done before selling it) - please see http://support.apple.com/kb/ts4515
If you are unable to contact him to do this then I'm afraid you will not be able to use the device - there is no other way of unlocking it at all. Apple cannot unlock it for you.
You should if possible return it to wherever you bought it and ask for a refund as in this event the device is completely useless.
