If you have a phone that was activated with a Google account previously, you will need that information. Security will not let you do anything.
Welcome to Android Central! methodman89 is correct -- you need the previous owner's information (which will be difficult if not impossible to get). Contact the seller and ask for a refund. We can't help you bypass this security feature.
