Complaint:

Made 7 sales calls in one morning

Who leaked my personal information

Wang Xiaoqiang (pseudonym) is from Zhejiang Qiandaohu, a small construction site owner, returned to his hometown to take over work a few years ago.

On January 10, he went from his hometown construction site to Hangzhou to see his children. At nearly 1 o'clock at noon, the family of three went to eat near Wushan Square after visiting Leifeng Pagoda. In just one morning, he received 7 calls, basically all sales calls. Wang Xiaoqiang said that one of the numbers promoting silver financial management called him three times in a row, which made him very disgusted. "When the third call came, I just pressed it down. My wife started to have objections, and it took me a long time to explain her concerns."

When he came home in the afternoon, Mr. Wang was in a depressed mood, thinking about the past half-century. During the past month, he kept receiving calls from gold shops, silver investments, and senior manager training courses. On several occasions, he almost got into a car accident just to answer these calls. He always had a question in his mind: How did these people know my mobile phone number?

When he called back, he would either get the answer "This number does not exist", or the other party would just say "You don't care how I know your number." He summarized that these calls have several characteristics:

First, these calls are basically from outside area codes or starting with 400, and they have been dialed frequently in the past half month;

Second Second, the other party knows that he is a boss, but does not know his specific occupation;

Third, the other party knows the specific address of his home in Hangzhou, but does not know his height, height, weight, and thinness;

Fourth, the other party knew that he owned a BMW car, but did not know the license plate number.

Of course, there is another characteristic. Everyone who calls knows his personal information very well, but he does not know anyone.

"How do these people know my name and family situation? I have received sales calls before, but there is not so much information." Wang Xiaoqiang suddenly remembered something: a month ago, he was A bank in Hangzhou applied for a Supreme Card. "Did the bank leak my personal information?" When he complained to the media, he said, if his guess came true, then how many people would be receiving sales calls as frequently as him every day.
