The iPhone has been activation locked by the previous owner and cannot be bypassed. Activation lock is an anti-theft measure and only the previous owner can remove the lock. Without assistance from the previous owner, the iPhone is useless to you or anyone else. You might try to get your money back - that is about all you can do at this point.
