听力原文:W: This is New Horizon customer service. Can I help you? M: This is Franklin speaking. I bought a watch from your shop a few days ago. But I found it didn't work this morning. I'm really confused. I don't know what I should do. W: Don't worry, sir. You can bring the watch to our store again and we will check it up and find the problem. Remember to bring back the receipt and the warranty certificate. M: Ok, thanks a lot. What is the man's problem?
