So you told them the box wasnt tampered with and told them nothing was in the box? Sounds like you messed up the SE I would hire someone to fix it for you because investigation usually last a week or 2 and depending on the situation they can refuse a refund or replacement. In an event that this would happen I would return the macbook to the apple store within the 15 day return policy and restart a few weeks later. But the rumor is is that Apple is patching the method so I wouldn't wait to long.
