Ask the person who called you where they saw it, then log in to the website immediately and notify their customer service or administrator to delete your information. Sometimes your information is reprinted, maybe by some websites that you don’t know about. The above method is more passive. The power of the Internet is very scary now. You can also search using your phone number on some search websites. If there is anything about you Information, enter the deletion or notify the website to delete. If that doesn't work, you can only tell them when you answer the phone. The house is sold to avoid repeated interruptions from the same company. There is no absolute way.
