There is an extra ticket for no reason. Has personal information been leaked?

This possibility is not ruled out. After the disclosure of personal information, spam messages, harassing calls and fraudulent calls followed, which seriously affected daily life.

According to the Personal Information Protection Law of People's Republic of China (PRC), no organization or individual may illegally collect, use, process or transmit other people's personal information, or illegally buy, sell, provide or disclose other people's personal information. Do not engage in activities that endanger network security, infringe upon the legitimate rights and interests of others, and endanger the interests of the public. I suggest you consult a professional lawyer to understand your rights and responsibilities.
