I sold a brand new, sealed tablet last week for $200. This was my return policy: "No returns or exchanges, but item is covered by eBay Buyer Protection" Today he sends me this email: I set up the tablet tonight and it froze up I cannot shut it off or do anyrthing with it I tried calling the assistance number that was in the box but the number is no longer in service and no fowarding number was listed. I am unhappy with this product what can we do to fix the problem. Thank you What should I do here? I'm thinking of not even responding to him... .
