What funny scam calls have you received?

Last year, I received a fraudulent phone call, posing as the company leader. I asked him who he was. He said he was the leader, so let me listen to him. Because I just remembered the voice of the company leader, I guessed XXX, and then the liar called himself XXX, and then made an appointment to find him to run the company the next day. Here comes the point. The next day, about 15 minutes before the appointed time, let me wait and then ask if I have any cash to tip the guests. I immediately became suspicious and said no, then he said Alipay could, and I blew it up in an instant and scolded a few words. Then the liar called again today. Let me guess. I talked with him for half an hour. Finally, I called him and said that I was seeing the guests off and wanted to give them to him.
