On March 5, he contacted me in the name of sending the wrong message on WeChat. Later, we developed into a relationship. He taught me how to invest in gold. He introduced his friend, investment broker, Mr. He to me. On April 7th and 8th, I transferred about 10,000 US dollars to the Japanese bank personal account designated by Mr. He. I followed his trading and made a profit of 7,800 US dollars three times. I did not withdraw money because he said there was still a big market and more funds needed to be invested. But no more money was invested. At about four o'clock in the morning on May 6, he sent a message saying that he was going to die and asked me to forget him. Then he lost contact. On the same day, Mr. He also lost contact after I said I wanted to withdraw money. On May 7, I applied for a withdrawal of US$7,000, but it was not processed. Customer service can't be contacted either. I believed him till yesterday, but now I realize that I was deceived.
