On the night of January 6, I booked a flight ticket on kiwicom, and then my flight information was sent to a Chinese public mailbox and a Chinese mobile phone number. I later received an unknown threatening phone call from China. I immediately contacted kiwicom to cancel my flight. As a result, they responded that there would be no refund for canceled flights. At the same time, they denied that my personal information was sent to China. Even when I showed them screenshots of the email and Chinese mobile phone number they sent to China, they still denied it. I reported the matter to the European Union police. The European Union police responded that they had accepted the case. However, searching for related keywords such as kiwicom found that similar things happened to people every day. I hope that if you encounter the same situation, you will actively report it to the European Union police. In this way, more people will be more likely to cause the relevant EU agencies to thoroughly investigate the illegal behavior of the website.
