The hotel called me and said that I had booked a hotel. I know the name, but I didn't book it at all. What happened?

There may be several situations that cause the hotel to call you, but the following are some possible reasons:

1. Incorrect reservation information: It is possible that someone else used your name and phone number when booking a hotel, or the hotel entered the information incorrectly, resulting in contacting the wrong person. If you are sure that you have not booked a hotel, you can provide your identification to the hotel staff to prove that you are not booking.

2. Fraudulent phone calls: Some fraudulent phone calls may use your personal information to make you believe that they are employees of hotels or other organizations, thus defrauding you of financial information or money. If you suspect that this is a fraudulent phone call, you should contact the local police or consumer protection agency immediately.

3. Data leakage: It is possible that your personal information has been leaked and used through the online black market or other means. If you are worried that your personal information will be leaked, you should immediately monitor your bank account and credit report, and change your password to ensure the security of your account.

No matter what happens, you should contact the hotel as soon as possible and tell them your doubts. They will be able to help you clarify things and take appropriate measures to protect your personal information and rights.
