What to do when tracking information does not update?

I sold a Darth Revan minifigure on ebay and dropped off the item on May 5th (Sold May 4th). Tracking information is still stuck at electronic shipping info received with no further update. Today, the buyer opened an item not received case. I responded and told the buyer that I will contact USPS. USPS said to just wait. If it doesn't show up in a couple of days, there is nothing I can do without insurance. Has anyone experienced similar situation? I am planning on messaging the buyer and ask him to wait until May 15th (last day before buyer can escalate the claim), and if the item does not show, I will either refund the money or ship another Darth Revan minifigure. This is my first LEGO ebay selling experience, so any help or advice is appreciated.
