Recently I sold a new smartphone on eBay to a buyer with excellent feedback (600+ 100%) and thought everything went smoothly. Then suddenly the buyer initiates a return claiming the earphone jack on the phone is broken. Obviously I am suspicious that he's either making it up cause he doesn't like the phone or maybe dropped it and broke it himself. eBay is basically threatening to intervene if I don't accept the return and issue a refund. The problem is that I'd be out a lot of money if I accept the return. I'd be out shipping costs both ways ($30) and since the phone is now used, I can no longer sell it as new ($170 lost in value). So I'd be out $200. So I am planning on rejecting the return on the grounds that I did state in my listing that I do not accept returns and that if it's really broken he should contact the manufacturer. Not sure if it's covered under manufacturer warranty since I bought it on eBay. But if they don't require a receipt he should be able to fix it under warranty. Anyways, anyone have any tips or advice on how I should go about building my case? Currently, eBay is asking me to respond to the return request with: 1. Approve return 2. Refund money 3. Offer partial refund 4. Send the buyer a message. I guess I'll be choosing option 4 but what should I say to him?
